SDS PAGE and Western BlotProtocol

Laboratory - Day 1

• Bring in fish samples.• Analyze relatedness among samples using

the phylogenic charts.• Complete Laboratory Day 1 protocol

– Laemmli sample buffer• Solubilize the proteins in the fish muscle samples• Tris buffer, SDS, bromophenol blue, and glycerol.

– Molecular weight marker– Actin and myosin standard

Lab - Day 1: Extract and Denature FishProteins

Lab Day 2: Gel loading, running andstaining

• Defrost the protein extracts.• Prepare the electrophoresis chamber• Prepare the pre-cast gel and lock it into the

electrophoresis chamber.• Load and run the gel.

– 1x TGS buffer Tris-glycine-SDS• Stain the gel

– Coomassie stain
