that this may be computed directly by rearrangement of the Beer-Lambert law to   = A/C EQUATION G.2 This value can be calculated for each reading and the average taken as the value of variant. Remember that this value is a constant

Antibody Precipitation with Protein A or G

. Then incubate the complex-bound immobilized protein A or G for 5 minutes at 95°C with 25µl of the SDS-PAGE sample buffer. Centrifuge the sample and collect the supernatant. Repeat, pooling supernatant for a total of 50µl. The sample is now ready
