Mfr.No.	PKSH031403
Description	A DNA sequence encoding the human HPRG (NP_000403.1) (Met 1-Lys 525) with a C-terminal polyhistidine tag was expressed.
Alternative Names	HPRG;HRGP;THPH11
Reconstitution	Please refer to the printed manual for detailed information.
Background	Histidine-rich glycoprotein, also known as HRG and HPRG, is a glycoprotein located in plasma and platelets, and contains an unusually large amount of histidine and proline. In human, five distinct domains are recognized in the mature HPRG molecule. There are two N-terminal cystatin-like modules (aa 19 - 254) and one His-Pro-rich region (aa 350 - 497) that is flanked by two Pro-rich segments (aa 276 - 321 and 498 - 525). The His-Pro-rich region contains 10 tandem repeats with an HHPHG motif, and the N- and C-termini are linked by a disulfide bond. The specific functions of HRG remain unclear, but it is known that the protein binds heme, dyes and divalent metal ions. It inhibits rosette formation and interacts with heparin, thrombospondin and plasminogen. Two of the protein's effects, the inhibition of fibrinolysis and the reduction of inhibition of coagulation, indicate a potential prothrombotic effect. HPRG is evolutionarily, functionally and structurally related to cleaved high molecular weight kininogen (HKa), an anti-angiogenic polypeptide that stimulates apoptosis of proliferating endothelial cells through binding to cell-surface tropomyosin. The antiangiogenic activity of the multidomain plasma protein HPRG is localized to its histidine-proline-rich (H/P) domain and has recently been shown to be mediated, at least partially, through binding to cell-surface tropomyosin in fibroblast growth factor-2-activated endothelial cells.
Reactivity	Human
Tag	C-His
Formulation	Lyophilized from sterile PBS, pH 7.4
Host	HEK293 Cells
Accession Number	NP_000403.1
Endotoxin Level	< 1.0 EU per ug as determined by the LAL method.
Bioactivity	Measured by its ability to support the adhesion of MOLT-4 human acute lymphoblastic leukemia cells. (Lamb-Wharton, R.J. and W.T. Morgen, 1993, Cell Immunol. 152: 544). Human HPRG immobilized at 1 ug/ml (100 ul/well) will induce >65% MOLT4 cell adhesion (1 x 10E5 cells/well) in the presence of 7.5 ug/ml Concanvalin A.
Mol Weight	59 kDa
Mw(kda)	59 kDa

Sequence Info	Met 1-Lys 525

Shipping	This product is provided as lyophilized powder which is shipped with ice packs.
Stotage Note	Lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Purity	> 97 % as determined by reducing SDS-PAGE.
