Src基因家族的膜相关蛋白酪氨酸激酶包括c-Src、c-Yes、Fyn、Lck、Hck、Lyn、Blk和c-Fgr。人类Lck基因编码一种特定的淋巴细胞酪氨酸激酶,称为pp56 Lck。Lck基因的重排和过表达发生在特定的鼠类淋巴瘤中。人类淋巴瘤和神经母细胞瘤通常在基因组的Lck基因位点内表现出染色体异常。静息态的T细胞含有高水平的Lck蛋白和mRNA,这两者在T细胞被激活时均会下降。Lck的表达可能有助于某些类型肿瘤疾病的发生。Csk在Tyr 505位点上磷酸化Lck,这种磷酸化事件在某些条件下会抑制Lck的催化活性。而Lck在Tyr 394位点上的磷酸化会刺激Lck的活性,且不受Tyr 505磷酸化状态的影响。在T细胞抗原受体结合及其后续信号传导的响应下,Lck会在包括Tyr 192、Ser 59和Ser 194在内的残基上发生磷酸化。

I am using p-Lck (pY505.4): sc-136184 antibody for immunoprecipitation, how much antibody should I use?

Asked by: jenniferc
Thank you for your question. We recommend using 1–10 µl (i.e., 0.2–2 µg) of antibody with 1 ml of cell lysate. However, optimal antibody concentration should be determined by titration.
