I searched Sigma, Abcam, CST, and Antibodypedia for IP antibodies that can target ribosomal proteins (RPL1-46 and RPS1-33), but I could only find antibodies with WB functionality, and some IP antibodies target other species. I really need a catalog number for IP antibodies that can target ribosomal proteins from Saccharomyces cerevisiae, regardless of the specific ribosomal protein. Thank you, everyone!
