Assay Method Information

Assay Name:  ELISA assay
Description:  The studies began by screening for the optimal protein concentrations for the method. The studies were conducted in goat anti-mouse IgG coated black React-Bind 96 welled-plates (R&D Biosystems), referred to herein as the anti-mouse IgG plate. Twelve stock solutions were prepared containing a 1:1 stoichiometric mixture of gp120 and α4β7 integrin in PBS at pH 7.2 as given by 0 μM or control, 0.001 μM, 0.01 μM, 0.01 μM, 0.05 μM, 0.1 μM, 0.5 μM. 1 μM, 2.5 μM, 5 μM, 10 μM and 25 μM in protein (step 1, FIG. 1). A 200 μL aliquot of each stock solutions was then loaded across a 96 welled plate and treated either with 20 μL of PBS pH 7.2 (control) or 20 μL of a 100 μM stock solution of repandusinic acid (RA: compound whose anti-HIV activity is to be tested) in PBS pH 7.2 containing 1% DMSO. Three repetitions were run for both the control and positive or repandusinic acid treated experiments. The final concentration of repandusinic acid in each positive well was 10 μM. The plate was incubated for 4 h at 4° C. on a plate mixer at a speed that created a vortex in each well.
