VTCN1 Protein (AA 29-258) (His tag,AVI tag,Biotin)

Catalog No. ABIN4949004

Product Details

Target: VTCN1 (V-Set Domain Containing T Cell Activation Inhibitor 1 (VTCN1))

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: AA 29-258

Origin: Human

Source: HEK-293 Cells

Purification tag / Conjugate: This VTCN1 protein is labelled with His tag,AVI tag,Biotin.

Application: Functional Studies (Func)

Brand: MABSol®,PrecisionAvi

Sequence: AA 29-258

Specificity: Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

Characteristics: This protein carries an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag. The protein has a calculated MW of 28 kDa. The protein migrates as 45-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Purity: >90 % as determined by SDS-PAGE.

Endotoxin Level: Less than 1.0 EU per μg by the LAL method.

Application Details

Comment:

Ready-to-use AvitagTM biotinylated protein:
The product is exclusively produced using the AvitagTM technology. Briefly, a unique 15 amino acid peptide, the Avi tag, is introduced into the recombinant protein during expression vector construction. The single lysine residue in the Avi tag is enzymatically biotinylated by the E. Coli biotin ligase BirA.

This single-point enzymatic labeling technique brings many advantages for commonly used binding assays. The biotinylation happens on the lysine residue of Avi tag, and therefore does NOT interfere with the target protein's natural binding activities. In addition, when immobilized on an avidin-coated surface, the protein orientation is uniform because the position of the Avi tag in the protein is precisely controlled.

Background: V-set domain-containing T-cell activation inhibitor 1 (VTCN1) is also known as Immune costimulatory protein B7-H4, Protein B7S1, T-cell costimulatory molecule B7x, B7H4, which belongs to the immunoglobulin superfamily and BTN/MOG family. VTCN1 contains two Ig-like V-type (immunoglobulin-like) domains. The expression of VTCN1 is up-regulated by IL6 and IL10 and is inhibited by GM-CSF and IL4 on antigen-presenting cells (APCs). VTCN1 / B7-H4 negatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity. VTCN1 involved in promoting epithelial cell transformation.
