RLq-10	42			800	80	1
	134			800	160	1
Anti-MuLV pAb				16,000	32,000	64,000
Anti-Env pAb				10,000
Anti-His Mab				0.039 nM		1.18 nM
Anti-p30 Mab						0.56 nM

Antibody titers were determined by the three direct gp70, p15E and p30 CMIAs on samples serially diluted with negative normal human plasma, and expressed as the reciprocal of the bleed dilution giving a reactive result. For comparison, detection limits of the anti-His and anti-p30 monoclonal antibodies were also listed.
