Thawed aliquots may be stored at 2-8°C up to 3 months.
Gene Name	erb-b2 receptor tyrosine kinase 2
Database Link	Entrez Gene 2064 Human UniProt ID P04626
Background	erbB4. ErbB2 homodimers are not favored due to the lack of an erbB2 specific extracellular ligand. Heterodimerization with EGFR or erbB4 leads to activation of the intrinsic tyrosine kinase activity of EGFR or erbB4 resulting in phosphorylation of multiple tyrosine residues within the erbB2 intracellular domain: Tyr 1023, Tyr 1112, Tyr 1139, Tyr 1196, Tyr 1222, and Tyr 1248. Transphosphorylation via src family kinases leads to phosphorylation of Tyr 877, via PKC of Thr 686, via CamKinase2 of Ser 1113. Phosphorylation of Thr 686 and Ser 1113 interferes with erbB2 endocytosis and degradation.
Synonyms	HER-2, NEU, p185erbB2, NGL, c-erbB-2, MNL19
Note	Mol. weight: 185 kDa Protocol: Positive Control Provided. Cell lysate from EGF-treated SKOV-3 cells Description: Cell lysate from EGF-treated SKOV-3 cells, ovary adenocarcinoma (Human) Format: Lyophilized cell lysate from serum starved EGF-treated SKOV-3 cells. Reconstitution:Restore by addition of 200 µl H20. After complete solubilization add 200 µl 2x SDS-PAGE sample buffer, mix and incubate at 90°C for 5 min. Storage: Aliquote and store frozen. Avoid repeated freeze/thaw cycles. Application: The positive control cell lysate is recommended for immunoblot applications. 20 µl of positive control cell lysate correspond to ca. 80.000 cells. Use 20 µl / lane (mini gel) for HRPO/ECL detection of the target proteins. Please note: The lyophilized cell lysates contain SDS and are not recommended for applications with native proteins such as immunoprecipitation.
