表達(dá)區(qū)間及表達(dá)系統(tǒng)(Source)
Biotinylated Human IGSF8 Protein, Avitag,His Tag (IG8-H82Q3) is expressed from human 293 cells (HEK293). It contains AA Arg 28 - Thr 579 (Accession # Q969P0).
Predicted N-terminus: Gly
蛋白結(jié)構(gòu)(Molecular Characterization)

This protein carries an Avi tag (Avitag?) at the N-terminus, followed by a polyhistidine tag.
The protein has a calculated MW of 62.1 kDa. The protein migrates as 65-70 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
標(biāo)記(Labeling)
Biotinylation of this product is performed using Avitag? technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白標(biāo)記度(Protein Ratio)
Passed as determined by the HABA assay / binding ELISA.
內(nèi)毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
純度(Purity)
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
IGSF8 (Immunoglobulin superfamily member 8) is a member the EWI subfamily of the immunoglobulin protein superfamily, also known as EWI-2, KCT-4, LIR-D1, and PGRL. It interacts with the tetraspanins CD81 and CD9 and may regulate their role in certain cellular functions including cell migration and viral infection. IGSF8 suppresses T-cell mobility coordinately with CD81, associates with CD82 to suppress prostate cancer cell migration, regulates epidermoid cell reaggregation and motility on laminin-5 with CD9 and CD81 as key linkers. It may also play a role on integrin-dependent morphology and motility functions, and may participate in the regulation of neurite outgrowth and maintenance of the neural network in the adult brain. Recent research indicates that IGSF8 is highly expressed on malignant cells with antigen presentation defects, and it interacts with NK receptors to suppress NK cell cytotoxicity.
