A monoclonal antibody to human lens 21,000 molecular weight gamma crystallin has been produced in rat x mouse hybridoma cell lines. The antibody reacts specifically with the 24,000 molecular weight gamma crystallin and does not cross react with the 21,000 or the 19,000 gamma crystallins. The antibody reacts with protein from dog, mouse, monkey and bovine lenses but does not react with proteins from chick lens. The 24,000 molecular weight gamma protein increases from 2% of the soluble protein in the fetal lens to 14% in the 2 month old lens to 25? in the adult lens. No difference was observed in the amount of this crystallin between the nuclear and cortical regions of the adult lens. In one hypermature cataractous lens, the amount of this crystallin decreased to a value of about 5% of the total soluble protein.
