Thank you once again for your enquiry. I am pleased to forward you some futher procedure details for testing of ab in cell culture. I hope this will be helpful to you. 1. Resuspend 3T3 cells (passage#38) in regular culture media with 10% calf serum. Transfer 100ul culture/well to assay plate (5,000 cells/well). Incubate overnight. 2. Complete media change. Replace with 100ul media containing 0.5% calf serum. Incubate overnight. 3. Complete media change. Replace with media containing 0.5% calf serum. 4. Serial dilute h-TGF-alpha in media with 0.5% calf serum. 5. Transfer 100ul diluted cytokine cells to assay plate. Volume of each well is 200ul, containing 0.5% calf serum and h-TGF-alpha. Incubate 45 hours. 6. Add 20ul of Substrate Cell Titer 96 Aqueous One Solution Reagent to each well. 7. Incubate 37oC and read at OD 490nm. Should you have any further questions, please do not hesitate to contact us.
