Updated project metadata. Immunoprecipitation for RBPMS in human embryonic stem cells. Triplicates of sheep anti-rabbit beads coupled with rabbit anti-RBPMS antibody were compared with and triplicates sheep anti-rabbit beads, which served as IgG control. Bands above heavy IgG, between heavy IgG and light IgG, below IgG and both IgG bands combined were excised from a gel and labeled via dimethyl labeling, before LC-MS run to increase detection resolution.
