2d-nephge/sds-page analysis of tal-1b5 immunoprecipitates from [ 35s ] -methionine biosynthetically labelled cells revealed the presence of a number of alpha-chain spots in association with beta-chain products of three previously described loci ( beta-1 , beta-2 , beta-3 ) suggesting that this antibody recognizes an antigenic site common to those human ia alpha-chains so far identified .
