| 产品介绍 | background: The Maspin protein is a sour depressant of nenzyme of a kind of silk ammonia that represses the tumor, is the sour depressant of protei nenzyme one member within super household of the silk ammonia, it is in repress the tumor growth and transfer exertive certain function. Function: Tumor suppressor. It blocks the growth, invasion, and metastatic properties of mammary tumors. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity. Subunit: Interacts with IRF6. Subcellular Location: Secreted, extracellular space. Tissue Specificity: Normal mammary epithelial cells. Similarity: Belongs to the serpin family. Ov-serpin subfamily. Database links: Entrez Gene: 5268 Human Entrez Gene: 20724 Mouse Entrez Gene: 116589 Rat Omim: 154790 Human SwissProt: P36952 Human SwissProt: P70124 Mouse SwissProt: P70564 Rat Unigene: 55279 Human Unigene: 268618 Mouse Unigene: 25752 Rat Important Note: This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications. Maspin蛋白是一种抑制肿瘤的丝氨酸蛋白酶抑制剂, 是丝氨酸蛋白酶抑制剂超家族中的一员,它在抑制肿瘤生长和转移中发挥一定作用。 |

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。
