Antibody pair for SARS-CoV-2 Spike protein (COVID-19, 2019-nCoV). Capture is rabbit anti-S1 spike protein domain. Detection is HRP-conjugate of chicken anti-S2 spike protein domain.

Sufficient material for: 5 X 96 well plates.

Catalog ab-131-295-PAIR

Figure 1: ELISA test COVID-19 spike protein using antibody pair ab-131-295-PAIR. Antibodies: Rabbit anti-spike protein S1 was coated at a dilution of 1/1000 in PBS for 1 hour at room temperature. After blocking, calibrator was diluted from 2000ng/ml to 15ng/m1 in blocking buffer and incubated for 1 hour on coated plate. After washing detection antibody (Chicken anti-spike protein S2 – HRP) was diluted 1/1000 in blocking buffer and incubated on the calibrator wells for 1 hour. After a final wash and tamping, the ELISA was developed by the addition of 100u1TMB to each well and stopped after 15 minutes by the addition of 0.2M sulfuric acid.
