Human Immunodeficiency Virus type 1 (HIV-1) gp120 / Glycoprotein 120 ELISA Pair Set

Sino Biological

short description

The HIV-1 gp120 / Glycoprotein 120 ELISA Pair Set is for the quantitative determination of HIV-1 gp120 / Glycoprotein 120. The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for HIV-1 gp120 / Glycoprotein 120 coated on a 96-well plate. Standards and samples are added to the wells, and any HIV-1 gp120 / Glycoprotein 120 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-HIV-1 gp120 / Glycoprotein 120 monoclonal antibody is then added, producing an antibody-antigen-antibody "sandwich". The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of HIV-1 gp120 / Glycoprotein 120 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.

detection target

gp120
Standard (antigene): Each vial contains 78 ng of recombinant HIV-1 gp120 / Glycoprotein 120. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20°C; to -80°C; in a manual defrost freezer. A seven-point standard curve using 2-fold serial dilutions in sample dilution buffer, and a high standard of 2500 pg/mL is recommended.
capture antibody type: 0.5 mg/mL of rabbit anti-HIV-1 gp120 / Glycoprotein 120 monoclonal antibody (in PBS, pH 7.4). Dilute to a working concentration of 2 µg/mL in PBS before coating. (Catalog: # 11233-R001)
detection antibody type: 0.2 mg/mL of rabbit anti-HIV-1 gp120 / Glycoprotein 120 monoclonal antibody conjugated to horseradish-peroxidase (HRP) (in PBS, 50 % HRP-Protector, pH 7.4, store at 4°C;). Dilute to working concentration of 0.5 µg/mL in detection antibody dilution buffer before use. (Catalog: # 11233-R011)
Lable: HRP

sensitivity

The minimum detectable dose of HIV-1 gp120 / Glycoprotein 120 was determined to be approximately 39.06 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
