II.Background
ERBB2 (HER2) A775_G776insYVMA results in the insertion of four amino acids in the protein kinase domain of the Erbb2 (Her2) protein between amino acids 775 and 776 (UniProt.org). A775_G776insYVMA results in the same amino acid change as M774_A775insAYVM, which leads to constitutive phosphorylation of Erbb2 (Her2) and is transforming in cell culture (PMID: 17311002, PMID: 29967253).

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細胞株



現代新藥研發的關鍵首先是尋找，確定和制備藥物作用靶點。在500多個已發現的藥物靶點里中，GPCR，Ion Channel，Kinase使用的最為廣泛。




激酶(kinase)是一類從高能供體分子（如ATP）轉移磷酸基團到特定靶分子（底物）的酶；這一過程謂之磷酸化。許多腫瘤的發生是由某些與生長相關的“激酶”發生突變導致異常活化引起的，因而針對這些突變激酶的抑制劑能夠有效抑制這些激酶的活性，從而達到抑制癌細胞增長的目的。
