I am currently growing stomach epithelial cells in T25 flasks and plan to seed them into a 96-well plate for treatment with specific conditions. For my next step, I need to perform an ELISA test for Vitamin B12 using a commercially available kit. However, I am unsure of the best approach to transfer all the cells or their supernatant from the 96-well plate to the wells of the ELISA plate provided by the kit without disrupting the cells or compromising the assay's accuracy.
