Immunoprecipitation: Lin28 Antibody (14E6-4E6) [NBP2-22481] - Immunoprecipitation of LIN28 was performed. Antigen-antibody complexes were formed by incubating 700ug of lysate with 5 ug of an LIN28 monoclonal antibody overnight on a rocking platform at 4C. The immune complexes were captured on 50 ul Protein A/G Agarose was loaded as a positive control for detection. Samples were resolved on a 4-20% Tris-HCl polyacrylamide gel, transferred to a PVDF membrane, and blocked with 5% BSA/TBS-0.1%Tween for at least 1 hour. The membrane was probed with a LIN28 monoclonal antibody at a dilution of 1:1000 overnight rotating at 4C, washed in TBST, and probed with Clean-blot IP Detection Reagent at a dilution of 1:1000 for at least 1 hour.
