BTN3A2 (Butyrophilin subfamily 3 member A2; also BTF3 and BT3.2) is a 36 kDa (predicted) glycoprotein, member of the BTN family, Ig Superfamily of molecules. Mature human BTN3A2 is a 305 amino acid (aa) type I transmembrane protein. It contains a 219 aa extracellular region with one V-type Ig-like domain and a 65 aa cytoplasmic tail. The cytoplasmic region undergoes phosphorylation on two serines. There are three potential splice forms. A rodent counterpart to BTN3A2 has not been reported. BTN3A2 mRNA overexpression was associated with a good prognosis in relation to disease-free and overall survival in a cohort of 55 epithelial ovarian cancer (EOC) patients . Another study in a larger cohort of 199 high-grade EOC patients further confirmed that the protein expression of BTN3A2 in ovarian cancer tissues is positively correlated with the intraepithelial infiltration of CD4+ and CD8+ T cells, suggesting that BTN3A2 was a co-stimulatory molecule to modulate the infiltration of immune cells and thus the anti-cancer immunity. Specifications Synonyms BT3.2; BTF3; BTF4; BT3.3; BTN3A2; FLJ40011; BTN3.2; CD277 Uniprot No. P78410.1 Source Recombinant Human BTN3A2 Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Gln30-Trp248. Molecular Weight Approximately 26.5 kDa. Due to glycosylation, the protein migrates to 27-33 kDa based on Tris-Bis PAGE result. Purity > 95% as determined by SDS-PAGE and HPLC. Endotoxin < 1.0 EU per 1μg of the protein by the LAL method. Formulation Lyophilized from 0.22 μm 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 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. Storage Transported with ice packs. Store at -20℃ to -80℃, valid for one year. After reconstitution, store unopened at -20 to -80°C for 3 to 6 months. After reconstitution, store at 2 to 8°C for 2 to 7 days.。 It is recommended to store in aliquots and freeze for the first use to avoid repeated freezing and thawing. Note 1. Avoid repeated freezing and thawing. 2. For your safety and health, please wear a lab coat and disposable gloves when operating. 3. This product is for scientific research purposes only.
