Assay Procedure
1.Seed 200 µL of 20,000 adherent cells in culture medium in each well of a 96-well plate.
2.Incubate the cells for overnight at 37°C, 5% CO2.
3.Treat the cells as desired.
4.Remove the cell culture medium and rinse with 200 µL of 1x TBS, twice.
5.Fix the cells by incubating with 100 µL of Fixing Solution for 20 minutes at room temperature.
6.Remove the Fixing Solution and wash the plate 3 times with 200 µL 1x Wash Buffer for five minutes each time with gentle shaking on the orbital shaker.
7.Add 100 µL Quenching Buffer and incubate for 20 minutes at room temperature.
8.Wash the plate 3 times with 1x Wash Buffer for 5 minutes at a time, with gentle shaking on the shaker.
9.Add 200 µL of Blocking Buffer and incubate for 1 hour at room temperature.
10.Wash 3 times with 200 µL of 1x Wash Buffer for 5 minutes at a time, with gentle shaking on the shaker.
11.Add 50 µL of 1x primary antibodies (Anti-CXCR4 (Phospho- Ser339) antibody, Anti-CXCR4 antibody and/or Anti-GAPDH antibody) to the corresponding wells, cover with Parafilm and incubate for 16 hours (overnight) at 4°C.
12.Wash 3 times with 200 µL of 1x Wash Buffer for 5 minutes at a time, with gentle shaking on the shaker.
13.Add 50 µL of 1x secondary antibodies to corresponding wells and incubate for 1.5 hours at room temperature with gentle shaking on the shaker.
14.Wash 3 times with 200 µL of 1x Wash Buffer for 5 minutes at a time, with gentle shaking on the shaker.
15.Add 50 µL of Ready-to-Use Substrate to each well and incubate for 30 minutes at room temperature in the dark with gentle shaking on the shaker.
16.Add 50 µL of Stop Solution to each well and read OD at 450 nm immediately using the microplate reader.
17.After finishing reading the absorbance at 450 nm, wash the plate twice with 200 µL of Wash Buffer and twice with 200 µL of 1x TBS for 5 minutes each. Tap the plates on paper towel to remove the excess liquid. Let plate air dry for 5 minutes at room temperature.
18.Add 50 µL of Crystal Violet Solution to each well, incubate for 30 minutes at room temperature on the shaker.
19.Flick the plate to remove Crystal Violet Solution, rinse the plate by filling the wells with running tap water, and wash the plate with 200 µL of 1x TBS 3 times, 5 minutes each with gently shaking on the shaker.
20.Add 100 µL of SDS Solution into each well and incubate on the shaker at room temperature for 1 hour.
21.Read absorbance at 595 nm with microplate reader.
Calculation of Results
Anti-ICAM-1 antibody normalization: The OD values obtained for the phosphorylated target protein can be normalized using the OD values obtained for the non-phosphorylated target protein via the proportion, OD450 (Anti-ICAM-1 P-Tyr512 antibody)/OD450 (Anti-ICAM-1 antibody).
Assay Precision
This ELISA kit is intended for research purposes only, NOT for diagnostic or clinical procedures of any kind.
Precaution of Use
Reagents provided in this kit may be harmful if ingested, inhaled or absorbed through the skin. Fixing Solution contains formaldehyde. Formaldehyde is known to be a highly toxic reagent. Personal protection is strongly recommended while working with this chemical.
