Description
  • Byli připraveny polyklonální protilátky proti 24-epicastasteronu. Protilátky byly připraveny imunizací králiků pomocí konjugátu 24-epicastasterone O-(carboxymethyl)oxime (24-epiCS-CMO) s hovězím sérovým albuminem (BSA). Dané protilátky byly použity pro vývoj ELISA testu pro stanoveni 24-epicastasteronu a příbuzných brssinosteroidů s detekčním limitem od 0.005 do 50 pmolů. Pro analýzu endogenních BRs byly použity rostliny fazole (Phaseolus vulgaris L., cv. Pinto), mrkve (Daucus carota ssp.sativus), Arabidopsis thaliana L. Heynh. A řepkový pyl (Brassica napus L.). Stanovení bylo prováděno pomocí HPLC-ELISA a HPLC-MS. (cs)
  • We have developed enzyme-linked immunosorbent assays (ELISAs) for measuring 24-epicastasterone and related brassinolide analogues, with detection ranges of 0.005 to 50 pmoles. Polyclonal antibodies used in these assays were raised against 24-epicastasterone carboxymethyloxime-bovine serum albumin conjugates and were found to have high specificity for 24-epibrassinosteroids. Natural brassinosteroids (BRs), such as brassinolide and 24-epibrassinolide, exhibited relatively high cross-reactivities with the generated antibodies, while other BR analogues with β-oriented hydroxyl groups at C-2, C-3, C-22, and C23 lacked immunoreactivity. Through the use of internal standardization, dilution assays, recovery of authentic [3H]24-epicastasterone, and immunohistograms, the ELISAs have been shown to be applicable for estimating 24-epibrassinosteroids levels in crude plant extracts. In order to analyze brassinosteroids in tissues from young bean (Phaseolus vulgaris L., cv. Pinto), Daucus carota ssp.sativus an
