of western blot filter paper to protect it from light exposure while drying. If the positive control lysate does not result in a positive signal, the western blotting protocol requires optimization. Store blots in the dark to prevent … Centrifuged, put on … Weigh certain … Drying the membrane allows for extended storage of the blot and can reduce exposure times. Western Blotting After determining cell lysate concentration, lysates (total of 50 ug protein) were mixed with sample buffer (two volumes) and heated on the heat block at 90 C for 10 min.

Alexa Portugal Audrey Peng MCB 253 15 October 2020 General Western Blot Protocol Background: The purpose of the General Western Blot Protocol is to identify proteins that have been separated based on their molecular molecular weight by gel electrophoresis. It will also verify that any negative results are indeed negative. It uses specific antibodies in order to identify these proteins, often from a mixture of proteins.
