Human CD28H / IGPR-1 Protein, Fc Tag

分子别名(Synonym)

TMIGD2,IGPR1

表达区间及表达系统(Source)

Human CD28H, Fc Tag (CDH-H5251) is expressed from human 293 cells (HEK293). It contains AA Leu 23 - Gly 150 (Accession # AAH15655.1).

Predicted N-terminus: Leu 23

蛋白结构(Molecular Characterization)

Online(Leu 23 - Gly 150) AAH15655.1

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 40.6 kDa. As a result of glycosylation, the protein migrates as 45-60 kDa under reducing (R) condition, and 90-120 kDa under non-reducing (NR) condition (SDS-PAGE).

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

电泳(SDS-PAGE)

Human CD28H, Fc Tag (Cat. No. CDH-H5251) SDS-PAGE gel

Human CD28H, Fc Tag on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

 

活性(Bioactivity)-ELISA

Biotinylated Human ELISA

Immobilized Human B7-H7, His Tag (Cat. No. B77-H52H5) at 5 μg/mL (100 μL/well) can bind Human CD28H, Fc Tag (Cat. No. CDH-H5251) with a linear range of 1-20 ng/mL (QC tested).

Protocol

背景(Background)

CD28 homolog (CD28H), also called transmembrane and immunoglobulin domain containing 2 (TMIGD2) and IGPR-1,is encoded by the TMIGD2 gene. CD28H is constitutively expressed on naive T and NK cells. After interaction of CD28 homolog with B7 homologue,the peripheral effector and memory T cells can be activated and proliferated by Akt-dependent signalling cascade. Plays a role in cell-cell interaction, cell migration, and angiogenesis. Through interaction with HHLA2, costimulates T-cells in the context of TCR-mediated activation. Enhances T-cell proliferation and cytokine production via an AKT-dependent signaling cascade.
