產品詳情
* 以下信息僅供參考,詳情請以原廠網站為準
  • 產品名稱:Fluorescein Maleimide, 12 mg

    別名:熒光素標記的馬來酰亞胺

    產品描述:

    Fluorescein Maleimide is designed for fluoresceinating proteins, nucleic acids or other molecules containing one or more thiol groups. Molecules to be labeled with Fluorescein Maleimide require free thiol groups. In the case of proteins, Fluorescein Maleimide will react with exposed cysteine residues. Alternatively, free thiols may be generated by reducing disulfide bonds or by modifying other reactive groups such as primary amines with compounds like Traut’s reagent (2-iminothiolane).For labeling nucleic acids, thiols can be introduced into DNA, RNA, or oligonucleotides using the FastTag?, 5′ EndTag™ or 3′ EndTag™ nucleic acid labeling systems.This fluorescent label can be directly detected or used as a hapten and detected with our high affinity antibody reagents. (Excitation maximum at 495 nm; emission maximum at 515 nm).

產品名稱:Succinylated Wheat Germ Agglutinin (WGA), Agarose bound, 5 ml

別名:琥珀?;←溑哐磕?,瓊脂糖交聯

產品描述:

Wheat germ agglutinin (WGA) succinylated has been reported to have properties distinct from the native lectin. Evidence suggests that Succinylated Wheat Germ agglutinin does not bind to sialic acid residues, unlike the native form, but retains its specificity toward N-acetylglucosamine. Using conjugates of the native lectin and the succinylated form can provide a system to distinguish between sialylated glycoconjugates and those containing only N-acetylglucosamine structures.Agarose bound*, succinylated WGA is prepared using our affinity-purified lectins. Heat stable, cross-linked 4% agarose beads with a molecular weight exclusion limit of about 2×107 daltons are used as the solid-phase matrix to which the lectins are covalently coupled. The attachment of the lectins to the beads is carefully controlled to preserve lectin activity and minimize conformational changes of the bound lectins that might result in nonspecific ionic or hydrophobic interactions. The technique we have developed to couple lectins to agarose beads inserts a hydrophilic spacer arm between the lectin and the matrix.This coupling method provides several advantages over the traditional cyanogen bromide procedure:Maximum carbohydrate binding activity of the coupled lectins is retainedLinkage is stable over a range of pH valuesConjugated proteins are not leached off the beads by Tris or other routinely used buffersNo residual charges are present after conjugation. This minimizes non-specific binding to the matrix.Our agarose bound lectins are supplied at a constant concentration of lectin per ml of settled beads. The concentration for each lectin is selected to achieve the highest glycoconjugate binding capacity per mg of lectin present in the beads. Each lot is tested for its binding capacity using glycoproteins known to bind the lectin. This provides a guideline for the user and assures the quality of our agarose bound lectins.Inhibiting/Eluting Sugar: Chitin Hydrolysate (Cat. No. SP-0090) or 500 mM N-acetylglucosamine with salt and/or acid elution generally required*3 mg lectin/ml gel

實驗應用:Glycobiology,Affinity Chromatography

推薦稀釋度:

Wash gel thoroughly with buffer before use to remove sugar added to stabilize the lectin. Recommended product for eluting glycoconjugates bound to this agarose-lectin: Glycoprotein Eluting solution, Cat. No. ES-5100. Alternatively, 0.5 M N-Acetyl-D-Glucosamine (GlcNAc) can be used.For those glycoconjugates having very high affinity for WGA, it may be necessary to lower the pH of the eluting sugar solution to pH 3.0 with acetic acid and increase the concentration of GlcNAc. After use, wash the gel with several column volumes of buffered saline, then resuspend gel in buffered saline containing 0.08% sodium azide for storage.

使用前用緩沖液徹底清洗凝膠,以去除為穩定凝集素而添加的糖。 用于洗脫與該瓊脂糖凝集素結合的糖綴合物的推薦產品:糖蛋白洗脫溶液,Cat. 編號 ES-5100。 或者,可以使用 0.5 M N-乙?;?D-氨基葡萄糖 (GlcNAc)。對于那些對 WGA 具有非常高親和力的糖綴合物,可能需要用乙酸將洗脫糖溶液的 pH 值降低到 3.0 并增加 GlcNAc 的濃度。 使用后,用幾柱體積的緩沖鹽水清洗凝膠,然后將凝膠重懸于含有 0.08% 疊氮化鈉的緩沖鹽水中保存。

產品詳情

產品名稱:Peanut Agglutinin (PNA), CY?3, 1 mg

別名:花生凝集素,Cy3標記

產品描述:

Cy3 PEANUT AGGLUTININ PNA binds preferentially to the T-antigen, a galactosyl (β-1,3) N-acetylgalactosamine structure present in many glycoconjugates such as M and N blood groups, gangliosides, and many other soluble and membrane-associated glycoproteins and glycolipids. With certain exceptions, the receptor sequence for PNA is normally sialylated which prevents the lectin from binding to its receptor oligosaccharide (see Jacalin). Even sialic acid which is not bound directly to the receptor sugars may inhibit binding. The presence of calcium ions in diluents can enhance the binding of PNA to receptors, possibly by neutralizing the negative charges on sialic acid residues adjacent to the receptor sequence.Cy3 labeled Peanut agglutinin has an appropriate number of fluorochromes bound to provide the optimum staining characteristics for this lectin. This conjugate is supplied essentially free of unconjugated fluorochromes.Excitation: 550 nmEmission: 570 nmColor: Red

  • 產品描述:
    Peanut agglutinin (PNA) binds preferentially to the T-antigen, a galactosyl (β-1,3) N-acetylgalactosamine structure present in many glycoconjugates such as M and N blood groups, gangliosides, and many other soluble and membrane-associated glycoproteins and glycolipids. With certain exceptions, the receptor sequence for PNA is normally sialylated which prevents the lectin from binding to its receptor oligosaccharide (see Jacalin). Even sialic acid which is not bound directly to the receptor sugars may inhibit binding. The presence of calcium ions in diluents can enhance the binding of PNA to receptors, possibly by neutralizing the negative charges on sialic acid residues adjacent to the receptor sequence.PNA is useful in distinguishing between normal and tumor tissues and in assessing malignancy in transitional mucosa. In addition, PNA binding can be used to measure cellular maturity in lymphoid tissues, to distinguish a variety of lymphocyte subpopulations in man and experimental animals, and to measure the levels of lymphoid cell populations in many diseases. PNA can be employed in the fractionation of stem cells in mice for use in bone marrow transplantation across histocompatibility barriers.A major cell surface receptor for PNA may be asialo GM1 ganglioside. Since PNA shares specificity with the antibody to this glycolipid, PNA and the antibody can be used interchangeably in some applications.Agarose bound* PNA is prepared using our affinity-purified lectins. Heat stable, cross-linked 4% agarose beads with a molecular weight exclusion limit of about 2×107 daltons are used as the solid-phase matrix to which the lectins are covalently coupled. The attachment of the lectins to the beads is carefully controlled to preserve lectin activity and minimize conformational changes of the bound lectins that might result in nonspecific ionic or hydrophobic interactions. The technique we have developed to couple lectins to agarose beads inserts a hydrophilic spacer arm between the lectin and the matrix.This coupling method provides several advantages over the traditional cyanogen bromide procedure:Maximum carbohydrate binding activity of the coupled lectins is retainedLinkage is stable over a range of pH valuesConjugated proteins are not leached off the beads by Tris or other routinely used buffersNo residual charges are present after conjugation. This minimizes non-specific binding to the matrix.Our agarose bound lectins are supplied at a constant concentration of lectin per ml of settled beads. The concentration for each lectin is selected to achieve the highest glycoconjugate binding capacity per mg of lectin present in the beads. Each lot is tested for its binding capacity using glycoproteins known to bind the lectin. This provides a guideline for the user and assures the quality of our agarose bound lectins.Inhibiting/Eluting Sugar: 200 mM galactose*5 mg lectin/ml gel

  • 花生凝集素 (PNA) 優先與 T 抗原結合,這是一種半乳糖基 (β-1,3) N-乙酰半乳糖胺結構,存在于許多糖綴合物中,例如 M 和 N 血型、神經節苷脂和許多其他可溶性和膜相關糖蛋白和糖脂。除了某些例外,PNA 的受體序列通常是唾液酸化的,這會阻止凝集素與其受體寡糖結合(參見 Jacalin)。甚至不直接與受體糖結合的唾液酸也可能抑制結合。稀釋劑中鈣離子的存在可以增強 PNA 與受體的結合,可能通過中和受體序列附近唾液酸殘基上的負電荷。PNA 可用于區分正常組織和腫瘤組織以及評估移行黏膜的惡性腫瘤。此外,PNA 結合可用于測量淋巴組織中的細胞成熟度,區分人和實驗動物中的各種淋巴細胞亞群,以及測量許多疾病中淋巴細胞群的水平。 PNA 可用于分離小鼠干細胞,用于跨越組織相容性障礙的骨髓移植。PNA 的主要細胞表面受體可能是去唾液酸 GM1 神經節苷脂。由于 PNA 與針對這種糖脂的抗體具有特異性,因此 PNA 和抗體可以在某些應用中互換使用。瓊脂糖結合* PNA 是使用我們的親和純化凝集素制備的。具有約 2×107 道爾頓分子量排除極限的熱穩定、交聯的 4% 瓊脂糖珠用作凝集素共價偶聯的固相基質。凝集素與珠子的連接受到仔細控制,以保持凝集素活性并最大限度地減少可能導致非特異性離子或疏水相互作用的結合凝集素的構象變化。我們開發的將凝集素與瓊脂糖珠偶聯的技術在凝集素和基質之間插入了一個親水性間隔臂。這種偶聯方法與傳統的溴化氰方法相比具有幾個優點:保持偶聯凝集素的最大碳水化合物結合活性pH 值范圍 結合的蛋白質不會被 Tris 或其他常規使用的緩沖液從珠子上浸出 結合后不存在殘留電荷。這最大限度地減少了與基質的非特異性結合。我們的瓊脂糖結合凝集素以每毫升沉降珠子的恒定凝集素濃度提供。選擇每種凝集素的濃度以實現珠中每毫克凝集素的最高糖綴合物結合能力。使用已知結合凝集素的糖蛋白測試每批的結合能力。這為用戶提供了指導并確保了我們瓊脂糖結合凝集素的質量。抑制/洗脫糖:200 mM 半乳糖*5 mg 凝集素/ml 凝膠
