Antigen used to elicit this antibody has been prepared in a following way: 1) intact chloropalsts from pea wee purified using Percoll density gradients 2) chloroplasts were hypotonically lysed and stroma was cleared of membranes by centrifugation 3) Rubisco Holoenzyme (L8S8) was isolated by sucrose density centrifugation 4) L8S8 complex was disrupted by pH shock and the L8 oligomer was precipitated 5) mature, folded Small subunit was further isolated by DEAE chromatography 6) It was considered pure by SDS-PAGE |
