HIV-1 Trimeric GP140 protein-clade A, BG505 strain
Catalog Number:
U90R79
Description:
A recombinant trimeric form of the HIV-1 glycoprotein (GP protein) from BG505 strain (clade A, GenBank: ABA61516.1) was produced by human embryonic kidney HEK293 cells, followed by Lectin purification. This product contains ectodomain of GP protein (end at D664) with furin cleavage site replaced by a linker, a T332N mutation for glycan, a I559P mutation for stable trimer formation, and C-terminal 8 hexa-histidine tag. This product has been evaluated by Size Exclusion Chromatography (SEC) to confirm the trimer formation, SDS-PAGE gel for purity and ELISAs for binding, see results. Due to the unique feature of BG505 at residue 241 glycan hole, a rabbit antibody 11B can target this protein (ref: Cell Rep. 2016;16(9):2327-38.), but not other HIV GP with 241N, such as YU2 (Catalog W44H24) or 16055 trimer (Catalog E7P43).
Applications:
Crystallization (Crys), ELISA, SDS-PAGE (SDS), Western Blotting (WB), Immunization or Antibody Sorting Probe

BSL-1
Organism:
HIV-1 (virus caused AIDS)
Size and Formulation:
100 or 500 μg in PBS, pH7.2, without preservatives.
