WebMar 3, 2024 · Lysates are then analyzed by western blotting and probed for the presence of a cargo protein modified with biotin, using fluorescently labeled streptavidin . In parallel, the lysates are probed for the presence of an HA tag, also fused to the cargo protein, which does not get modified during or after transport and thus reflects the total amount ... WebDec 2, 2024 · In this protocol, a mutant biotin ligase promiscuously labels proximal binding partners with biotin, and resulting biotinylated proteins are purified using …

WebDec 2, 2024 · Interestingly, the concentrations of SDS and IGEPAL-CA630 during the incubation with streptavidin conjugated beads were the key to effective elution of biotinylated proteins using excess biotin and heating. This protocol provides an alternative method to isolate biotinylated proteins from streptavidin conjugated beads that is … WebIncubate with the appropriate substrate solution for the recommended period of time (Bio-Rad suggests the use of DAB substrate with HRP-conjugated streptavidin, and Fast Red/Napthol AS-MX for Alkaline Phosphatase-conjugated streptavidin). Wash once in water. Counterstain with hematoxylin for 1 minute. “Blue” with running water for 5 minutes. WebIf SDS-PAGE buffer is selected for elution, the eluate will contain streptavidin monomers and dimers and biotinylated antibody along with target antigen. Note: Use the Thermo Scientific Clean-Blot IP Detection Reagent (Product No. 21230 or 21233) to prevent detection of the immunoprecipitation antibody in Western blots. reading a semen analysis
