Name :
Recombinant Human ERBB2 protein, His & T7-tagged
Specification :
| Description : This gene encodes a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. This protein has no ligand binding domain of its own and therefore cannot bind growth factors. However, it does bind tightly to other ligand-bound EGF receptor family members to form a heterodimer, stabilizing ligand binding and enhancing kinase-mediated activation of downstream signalling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase. Allelic variations at amino acid positions 654 and 655 of isoform a (positions 624 and 625 of isoform b) have been reported, with the most common allele, Ile654/Ile655, shown here. Amplification and/or overexpression of this gene has been reported in numerous cancers, including breast and ovarian tumors. Alternative splicing results in several additional transcript variants, some encoding different isoforms and others that have not been fully characterized. | Source : E. coli | Species : Human | Tag : His & T7 | Form : Freeze-dried powder | Molecular Mass : Predicted Molecular Mass: 42.2kDa. | Protein length : Thr23~Gly372 (Accession # P04626) | Endotoxin : | Purity : >90% | Characteristic : The isoelectric point is 5.9. | Applications : SDS-PAGE; WB; ELISA; IP. | Stability : The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition. | Storage : Avoid repeated freeze/thaw cycles. Store at 2-8°C for one month. Aliquot and store at -80°C for 12 months. | Storage Buffer : Supplied as lyophilized form in PBS, pH7.4, containing 5% trehalose, 0.01% sarcosyl. | Reconstitution : Reconstitute in sterile PBS, pH7.2-pH7.4.
