Specification

• Species: HIV
• Source: HEK293
• Tag: His
• Protein Length: 36-507 a.a.
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4.
• Bio-activity: Immobilized HIV-1 [HIV-1/Clade B/C (CN54)] GP120, His Tag at 5 μg/mL (100 μL/well) can bind Human CD4, Fc Tag with a linear range of 1-39 ng/mL.
• Molecular Mass: This protein carries a polyhistidine tag at the C-terminus.The protein has a calculated MW of 53.8 kDa. The protein migrates as 85-150 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• Storage: For long term, the product should be stored at lyophilized state at -20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after 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 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
