|A DNA sequence encoding the human GBP2 (AAH73163.1) (Met1-Cys588) was expressed with a polyhistidine tag at the C-terminus.|
|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.
|> 90 % as determined by SDS-PAGE|
|< 1.0 EU per μg of the protein as determined by the LAL method|
|Samples are stable for up to twelve months from date of receipt at -70℃|
|The recombinant human GBP2 consists of 599 amino acids and predicts a molecular mass of 68.3 KDa. It migrates as an approximately 62 KDa band in SDS-PAGE under reducing conditions.|
|Lyophilized from sterile PBS, pH 7.4|
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 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.
|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.|
|A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.|
GBP-2 belongs to the guanylate-binding protein (GBP) family. GBPs are characterized by their ability to specifically bind guanine nucleotides (GMP, GDP, and GTP). As GTPases induced by IFN-gamma (Interferon-inducible GTPase), they are key to the protective immunity against microbial and viral pathogens. GBP-2 is a GTPase that converts GTP to GDP and GMP. It binds GTP, GDP and GMP. GBP-2 hydrolyzes GTP very efficiently. GDP rather than GMP is the major reaction product. GBP-2 is induced by interferons that have antiviral effects and inhibit tumor cell proliferation.
