II.Background
ERBB2 (HER2), erb-b2 receptor tyrosine kinase 2, is an EGFR receptor tyrosine kinase that activates PI3K-AKT-mTOR and RAS-RAF-MEK-ERK pathways, therefore regulating growth and transformation (PMID: 17471238). ERBB2 (HER2) amplification, overexpression, and activation has been implicated in several tumor types (PMID: 17471238).


III. Representative Data

IV. Thawing

Thawing: Protocol
1. Remove the vial from liquid nitrogen tank and thaw cells quickly in a 37°C water-bath.
2. Just before the cells are completely thawed, decontaminate the outside of the vial with 70% ethanol and transfer the cells to a 15 ml centrifuge tube containing 9 ml of complete growth medium.
3. Pellet cells by centrifugation at 200 x g force for 5 min, and discard the medium.
4. Resuspend the cells in complete growth medium.
5. Add 10 ml of the cell suspension in a 10 cm dish.
6. Add promycin to a concentration of 1 μg/ml the following day.
Kinase细胞株



现代新药研发的关键首先是寻找，确定和制备药物作用靶点。在500多个已发现的药物靶点里中，GPCR，Ion Channel，Kinase使用的最为广泛。




激酶(kinase)是一类从高能供体分子（如ATP）转移磷酸基团到特定靶分子（底物）的酶；这一过程谓之磷酸化。许多肿瘤的发生是由某些与生长相关的“激酶”发生突变导致异常活化引起的，因而针对这些突变激酶的抑制剂能够有效抑制这些激酶的活性，从而达到抑制癌细胞增长的目的。
