Human immunodeficiency virus 1 / Strain: clade A/E / Cell line (production host): HEK GnT1- 293 cells / Production host: Homo sapiens (human) / References: UniProt: A0A0M3KKW9*PLUS #2: Antibody | Mass: 23991.855 Da / Num. of mol.: 2 Source method: isolated from a genetically manipulated source Source: (gene. exp.) Homo sapiens (human) / Cell line (production host): HEK 293 cells / Production host: Homo sapiens (human) #3: Antibody | Mass: 22193.434 Da / Num. of mol.: 2 Source method: isolated from a genetically manipulated source Source: (gene. exp.) Homo sapiens (human) / Cell line (production host): HEK 293 cells / Production host: Homo sapiens (human) Sequence details | The sequence of the clade A/E gp120 is based on the HIV-1 clade A/E gp120 sequence in PDB ID 3TGT. ...The sequence of the clade A/E gp120 is based on the HIV-1 clade A/E gp120 sequence in PDB ID 3TGT. The sequence was engineered to remove the outer domain of gp120 and consists of the N-terminal sequence plus some of the C-terminal sequence. | |
