Western Blot 第1阶段：样品制备
Novus Biologicals Visual Protocols: In phase 1 of the western blot procedure, you will learn how to prepare your samples before loading them into a gel. Here we isolate protein from cultured cells, quantify total protein concentrations with a BCA assay, add loading buffer to the sample, and heat the sample. Additional help can be found in the support section of http://www.novusbio.com, through our live chat service, or by calling us directly to talk with our elite customer and technical service scientists.
Western Blot 第2阶段：蛋白电泳(SDS-PAGE)
Novus Biologicals Visual Protocols: In phase 2 of the western blot procedure, you will learn how to load a gel and separate the proteins through electrophoresis, based upon protein weight. Additional help can be found in the support section of http://www.novusbio.com, through our live chat service, or by calling us directly to talk with our elite customer and technical service scientists.
Western Blot 第3阶段：膜转移
Novus Biologicals Visual Protocols: In phase 3 of the western blot procedure, you will learn how to transfer your proteins from the SDS-PAGE gel onto a PVDF or nitrocellulose membrane. Here we remove the gel from the cassette, and stack it in a sandwich comprised of a sponge, filter paper, the gel, membrane, filter paper, and sponge. The negatively charged proteins will then transfer onto the membrane toward the positive current.
