Biotinylated Human EGFRVIII Protein, His-Avi Tag

Description :
FAQ COA 已发表文献 The epidermal growth factor receptor (EGFR) subfamily of receptor tyrosine kinases comprises four members: EGFR (also known as HER1, ErbB1 or ErbB), ErbB2 (Neu, HER2), ErbB3 (HER3), and ErbB4 (HER4). The amino acid 25-378 of EGFR encodes the most common extracellular domain truncation mutant, termed EGFRvIII. It has been proved that EGFRvIII is relevant in a number of cancer types. EGFRvIII is tumor specific, and has not been found in normal tissues. EGFRvIII is highly tumorigenic, and can cause aggressive tumor phenotype, with increased invasion, proliferation, angiogenesis, and evasion of apoptosis. This EGFRvIII-mediated enhanced tumourigenicity combined with the lack of EGFRvIII expression in normal tissue makes it an ideal therapeutic targets. 产品性质 Synonyms ErbB; EC 2.7.10; EC 2.7.10.1; EGFR; mENA; LEGFR; ERBB; ERBB1; HER1; PIG61; NISBD2 Accession NP_001333870.1 Source Recombinant Biotinylated Human EGFRVIII Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Leu25-Ser378. Molecular Weight The protein has a predicted MW of 41.6 kDa. Due to glycosylation, the protein migrates to 65-78 kDa based on Tris-Bis PAGE result. Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Purity > 95% as determined by SDS-PAGE and HPLC Endotoxin 1.0EU per 1g of the protein by the LAL method. Formulation Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100g/mLis recommended. Dissolve the lyophilized protein in distilled water.
