| 产品介绍 | background: bov beta-lactoglobulin is the content of the milk in the category of a protein myosin. Protein contained in whole milk (3.7 percent) to 80% of the casein in the removal of the casein whey protein, 55% of the beta-lactoglobulin. Access to the crystallization of the isoelectric point = 5.2, the pH in this dual capacity under the main structure. The people in latex-free Beta-lactoglobulin. The beta-lactoglobulin and bov beta-lactoglobulinA-based. Function: Primary component of whey, it binds retinol and is probably involved in the transport of that molecule. Subunit: Under physiological conditions beta-lactoglobulin exists as an equilibrium mixture of monomeric and dimeric forms. Subcellular Location: Secreted. Tissue Specificity: Synthesized in mammary gland and secreted in milk. Post-translational modifications: Alternate disulfide bonds occur in equal amounts in all variants examined. Similarity: Belongs to the calycin superfamily. Lipocalin family. Database links: Entrez Gene: 280838 Cow SwissProt: Q32P89 Cow Unigene: 385 Cow Important Note: This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications. β-乳球蛋白是含于乳中的球蛋白类的一种蛋白质。牛乳中所含全蛋白(3.7%)的80%为酪蛋白,在除去酪蛋白的乳清蛋白质中55%为β-乳蛋白。 可获得其结晶,等电点=5.2,在此pH下主要成双量体结构。 而人的乳液中不含β-乳球蛋白。 该β-乳球蛋白与牛β-乳球蛋白A型基因、牛β-乳球蛋白B型基因、山羊和绵羊β-乳球蛋白基因的同源性分别为98.55%,99.79%,90.70%和90.09%。 |

文献和实验当FITC在碱性溶液中与抗体蛋白反应时,主要是蛋白质上赖氨酸的r氨基与荧光素的硫碳胺键(thiocarbmide)结合,形成FITC-蛋白质结合物,即荧光抗体或荧光结合物。一个IgG分子中有86个赖氨酸残基,一般最多能结合15~20个,一个IgG分子可结合2~8个分子的FITC,其反应式如下FITC-N=C=S + N-H2-蛋白质 → FITC-NS-C-N-H2-蛋白质常用Marsshall(1958)法标记荧光抗体,也可以根据条件采用Chadwick等标记法或Clark
ml三蒸水中即成; 方法与步骤: 根据Marshall氏法高效价的抗人球蛋白兔免疫血清,分离球蛋白。 1. 用0.15 mol/L NaCl的盐水及0.15 mol/L pH9.0的NaHCO3-Na2CO3缓冲液稀释使每毫升内含抗体10mg,缓冲液为总量的10%; 2. 将以上溶液降温至4℃,按蛋白:荧光素=50—80mg:1mg的比例加入异硫氰酸荧光素,在0—4℃下电磁搅拌12—14h; 3.用半饱和硫酸铵将标记球蛋白
5. 过柱。取透析过夜的标记物,过葡萄糖凝胶G-25或G-50柱,分离出游离荧光素,收集标记的荧光抗体进行鉴定。
