| Background | The Src family of protein tyrosine kinases, which includes Src, Lyn, Fyn, Yes, Lck, Blk, and Hck, are important in the regulation of growth and differentiation of eukaryotic cells (1). Src activity is regulated by tyrosine phosphorylation at two sites, but with opposing effects. While phosphorylation at Tyr416 in the activation loop of the kinase domain upregulates enzyme activity, phosphorylation at Tyr527 in the carboxy-terminal tail by Csk renders the enzyme less active (2). p56lck (lymphocyte cellular kinase) has been shown to be a pivotal enzyme to both maturation of thymocytes and activation and proliferation of peripheral lymphocytes. The p56lck sequence appeared highly homologous to that of the oncogene p60c-src as did its exon-intron organisation. p56lck does not appear involved in lymphoproliferative diseases, either by overexpression or activating mutations. Nevertheless, its aberrant expression has been reported in some carcinomas (colon, lung and mammary). It was suggested that p56lck could favor metastases by facilitating loss of cell adhesion (3). |

h）即可。2. 修复大法——不仅仅是「煮一煮」微波炉修复：简单易行效果好，CST 推荐使用微波炉完成修复。合适的修复液：根据抗体说明书使用合适的修复液。用柠檬酸修复后，切片需浸泡在修复液中，自然冷却；而用 EDTA 修复后，切片可直接从修复缸中取出，直接进行下一步。注：使用不同的修复方式和不同生产商的抗体检测人肺癌组织中 EGFR 的表达。第一排为 CST 的 EGF Receptor (D38B1) XP® Rabbit mAb（#4267），EDTA 的修复方式明显优于柠檬酸盐及胃蛋白
