产品介绍    background:
Protein tyrosine phosphatases (PTPases) SHP1 and SHP2 are critical regulators in the intracellular signaling pathways that result in cell responses such as mitosis, differentiation, migration, survival, transformation or death. SHP2 is a signal transducer for several receptor tyrosine kinases and cytokine receptors. A novel SHP2 associated glycoprotein was recently cloned from human, rat, mouse and cattle by several labs and was designated SIRPa (1),SHPS1 , MyD1, BIT and p84. SIRPa is a new gene family containing at least fifteen members. SIRPa is a substrate of many activated tyrosine kinases such as insulin receptor, EGFR, PDGFR and src, and a specific docking protein for SHP2. SIRPa has regulatory effects on cellular responses induced by serum, growth factors, insulin, oncogenes, growth hormones and cell adhesion and plays a general role in different physiological and pathological processes.


处理标本：
（1）将标本以5%福尔马林pH 7.2(4℃)PBS液固定40min～60min。
（2）用冷的PBS液洗涤，离心。
（3）如是组织块，则在解剖显微镜下切成更小块，放入试管中，加入铁蛋白－抗体结合物置室温20min，不时振荡,
（4）以冷PBS液洗涤三次，离心。
（5）沉淀以2.5%戊二醛固定20min，以PBS洗涤。
（6）再以锇酸固定，脱水包埋。也可以先超薄切片，再进行铁蛋白－抗体结合物染色。

单抗的制备过程：
1.动物免疫：注射特定抗原蛋白
2.分离脾淋巴细胞：与培养好的骨髓瘤细胞混合，人工诱导细胞融合。
3.细胞融合：淋巴细胞杂交瘤的制备
4.杂交瘤细胞的筛选：HAT选择培养基筛选出杂交瘤细胞。
5.培养杂交瘤细胞：体外培养杂交瘤细胞，从培养液中分离提取单克隆抗体。或者，将杂交瘤细胞移植到小鼠腹腔内，从小鼠腹水中分离提取单克隆抗体。
6.单克隆抗体的制备和冻存、纯化
