Overview:
LCK (p56lck) is a member of the src family of non-receptor tyrosine kinases. It was identified as a gene rearranged and overexpressed in the murine lymphoma LSTRA, most likely as a result of the insertion of Moloney murine leukemia virus DNA immediately adjacent to the gene (1). Lck behaves as a proto-oncogene and can lead to cell transformation upon activation. A number of human cancer cell lines show overexpression of LCK, pointing to a possible role for this kinase in the initiation and maintenance of the transformed state in human cancers (2).
Gene Aliases:
RP4-675E8.4, YT16, p56lck, pp58lck
Genbank Number:
NM_005356

最近遇到了实验上的大问题,就是用一步法做RNA的荧光定量PCR时,发现低浓度的做不出来,而DNA是可以的,想请问各位在一步法PCR中有没有什么高见,就是逆转录的Buffer有没有什么需要注意的地方!就是在逆转录酶的最适Buffer和Taq酶的最适Buffer中寻找一个最适的Buffer!

B、酶细胞产能细胞内(外)起作用消化酶细胞外起作用B错误;
C、酶同需要适条件同胃蛋白酶与胰蛋白酶所需PH同C错误;
D、葡萄糖细胞质基质解丙酮酸需要酶催化D确.
故选:D.
我是新手。我要开始做实验了,但一开始就碰到了个很大的问题。
我想买个能利用哺乳动物细胞RNA聚合酶将DNA转录成RNA的的质粒,向好几家公司打了电话,但都没有我想要的东西。
没有这个东西,我的实验就只能是蓝图了。哪位战友有办法的,能不能帮帮我?
不胜感激。
