10% APS and TEMED are an accelerator which should be rapidly mixed and poured into the device.Ġ.1g SDS is dissolved in 1 ml ddH 2O by heating to 56℃.Ġ.1 g APS is dispersed in 1ml ddH 2O and prepare when required. 0.1 g APS is dispersed in 1 ml ddH 2O and should be prepared when it will be used. Overloading protein can cause smearing.ĭissolved 0.1g SDS in 1ml ddH 2O by heating to 56℃. Add water for a total volume of 15 mlNote: loading amount of protein sample should be 10-40 μg per well. Add water for a total volume of 500 ml.įully dissolve the compounds.
Add water for a total volume of 500ml.įully dissolve the compounds. Then add water for a total volume of 500 ml and store in a brown bottle at RT.įully dissolve the compounds. When compared to a ladder or size marker (in kDA), protein size and expression can be determined.įully dissolve the compounds at 37℃. The membrane is then stained with a secondary antibody specific to the primary antibody, which can be detected by a variety of methods. The separated proteins are then stained by the PVDF or nitrocellulose membrane, and then blocked with milk (or another blocking reagent).
First, proteins are denatured and then separated by SDS-PAGE gel electrophoresis. Western blot (WB) is a technique used to identify and localize proteins based on their binding ability to specific antibodies.
