28A4, 27E8, 77F12, F1
MAbs 28A4 and 27E8 specifically recognize beta-subunit of HCG. MAbs are not cross-reacting with hLH, hTSH, hFSH.
MAb 77F12 specifically recognizes HCG; it reacts mainly with alpha-subunit. MAb is cross-reacting with whole molecule of HCG, hLH, hTSH and hFSH. Cross-reactivity with free beta-subunit of HCG was not detected.
MAb F1 is specific for the alpha-chain of FSH, LH, TSH and HCG.
