Recombinant Human PVR protein, C-mFc Tag
Product Description
Cat
IMP-080
Official Symbol
PVR
Product Overview
Recombinant Human PVR protein(AA Trp 21-Asn 343)(Accession # NP_006496.4) is expressed from human 293 cells (HEK293). This protein carries a mouse IgG2a Fc tag at the C-terminus.
Expression System
HEK293
Species
Human
Tag
C-mFc Tag
Form
Lyophilized from sterile Tris with Glycine, Arginine and NaCl, pH7.5, 10% trehalose.
Molecular Mass
The protein has a calculated MW of 62.2 kDa. As a result of glycosylation, the protein migrates as 70-100 kDa under reducing (R) condition, and 130-160 kDa under non-reducing (NR) condition (SDS-PAGE).
Protein length
Trp 21-Asn 343
Endotoxin
Less than 1.0 EU per ug by the LAL method.
Purity
>95% as determined by SDS-PAGE.
Storage
For long term storage, the product should be stored at lyophilized state at -20°C or lower. Please avoid repeated freeze-thaw cycles. This product is stable after storage at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
Reconstitution
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4ºC before opening to recover the entire contents.
