Product Description	Recombinant Human CD28H/IGPR-1 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Leu23-Gly150.
Product Background	CD28H is constitutively expressed on all naive T cells. Repetitive antigenic exposure, however, induces a complete loss of CD28H on many T cells, and CD28H negative T cells have a phenotype of terminal differentiation and senescence. After extensive screening in a receptor array, a B7-like molecule, B7 homologue 5 (B7-H5), was identified as a specific ligand for CD28H.
Product Category	Recombinant Protein / Antibody discovery

Protein	CD28H/IGPR-1
Synonyms	TMIGD2; IGPR1; IGPR-1; CD28H; TPC1
Accession	Q96BF3-1
Species	Human
Biotinylated	no
Amino Acid Range	Leu23-Gly150
Molecular Weight	The protein has a predicted MW of 15.1 kDa. Due to glycosylation, the protein migrates to 42-52 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human CD28H, His Tag at 5ug/ml (100ul/well) on the plate. Dose response curve for Human B7-H7, hFc Tag with the EC50 of 90.0ng/ml determined by ELISA. See testing image for detail.
Product Tag	C-His
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
