DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Human VSIG2 Protein Product Information
Synonym:UNQ2770/PRO7154, 2210413P10Rik, CTH, CTXL
Protein Construction:A DNA sequence encoding the human VSIG2 isoform 1 (Q96IQ7-1) extracellular domain (Met 1-Ala 243) was fused with a polyhistidine tag at the C-terminus.
Expressed Host:Human Cells
Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Human VSIG2 Protein QC Testing
Purity:> 95 % as determined by SDS-PAGE
Bio-Activity:Measured by the ability of the immobilized protein to support the adhesion of the HUVEC human umbilical vein endothelial cell line . When 4 x 10E4 cells/well are added to human VSIG2 coated plates (30 μg/ml, 100 μl/well), approximately 25 %-50 % will adhere after one hour at 37 ℃.
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:Val 24
Molecule Mass:The secreted recombinant human VSIG2 consists of 231 amino acids and has a calculated molecular mass of 24.6 kDa. The apparent molecular mass of rhVSIG2 is approximately 30-35 kDa in SDS-PAGE under reducing conditions due to glycosylation.
Formulation:Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
Human VSIG2 Protein Usage Guide
Storage:Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

VSIG2/CTXL Background

V-set and immunoglobulin domain-containing protein 2, also known as cortical thymocyte-like protein, CT-like protein and VSIG2, is a single-pass type I membrane protein which contains one Ig-like C2-type (immunoglobulin-like) domain and one Ig-like V-type (immunoglobulin-like) domain. VSIG2 is highly expressed in stomach, colon, prostate, trachea and thyroid glands and weakly in bladder and lung. V-set domains are Ig-like domains resembling the antibody variable domain. V-set domains are found in diverse protein families, including immunoglobulin light and heavy chains; in several T-cell receptors such as CD2 (Cluster of Differentiation 2), CD4, CD80, and CD86; in myelin membrane adhesion molecules; in junction adhesion molecules (JAM); in tyrosine-protein kinase receptors; and in the programmed cell death protein 1 (PD1).
