HIV-1 (IIIB Strain) gp120 Purified Native Glycoprotein
Catalog #: 14-102-050
Size: 50 µg
In Stock
Conformationally intact, fully glycosylated native gp120 glycoprotein of Human Immunodeficiency Virus type 1 (IIIB Strain). This viral protein was isolated from culture medium of HuT 78 (clone 6D5) chronically infected with HIV-1, lysed with 0.5% Triton X-100, and purified by immunoaffinity chromatography and reverse phase HPLC.
For research use only.

SHIPPING AND STORAGE:
This product is shipped frozen on dry ice. Store at -70°C upon receipt. Avoid multiple freeze-thaw cycles as product degradation may result.
RECOMMENDATIONS:
Upon thawing, centrifuge the vial for a few seconds to remove residual droplets from the lid.
SAFE HANDLING RECOMMENDATIONS:
This biological preparation should be handled in accordance with biosafety guidelines defined in the BMBL, NIH-CDC HHS Publication No. (CDC) 21-1112.
How are Advanced Biotechnologies Viral Proteins supplied? All proteins are supplied frozen on dry ice.
How are Viral Proteins purified? Our purification methodology varies according to the individual product requirements, as do the buffers in which the proteins are frozen.
How should Viral Proteins be stored? We recommend that all proteins be aliquoted into single-use size portions and stored frozen at -70°C or below. Avoid multiple freeze-thaw cycles as this will affect protein activity. Do not dilute and freeze – make final dilution just prior to use.
How are Advanced Biotechnologies Viral Proteins made? Native proteins are made in infected cells using cell culture. Recombinant proteins are made in various systems, generally yeast or baculovirus. All are screened for reactivity in ELISA and Western blot prior to selection.
Will Viral Proteins work in ELISA? All of our proteins work in ELISA. However, it is critical to use an appropriate primary antibody and conjugate dilution. Double-block titrations should be performed to determine the optimum use dilutions in your system.
Will Viral Proteins work in Western blot? All of our proteins work in Western blot according to the considerations mentioned for ELISA.
I’m getting good Western blot reactivity, but at the wrong molecular weight. What went wrong? It is not uncommon that different molecular weights are detected by electrophoresis due to different conformations. Please refer to the certificate of Analysis of each protein for its reported molecular weight.
How is the protein concentration of Advanced Biotechnologies Viral Proteins determined? A modified BCA protein assay is used with Bovine Serum Albumin (BSA) as the protein standard.
