Sequential sorting of viruses with antibodies against varying HIV-1 Env epitopes, measured by p24 capture in ng/p24 and as a percentage of p24 input

Capture mAb	First round capture		4B3 Depleted Second round capture		b12 Depleted Second round capture		2F5 Depleted Second round capture
	Input: 1000 ng		Input: 399 ng		Input: 491 ng		Input: 526 ng
	ng/p24	% input	ng/p24	% input	ng/p24	% input	ng/p24	% input
4B3	601	60.1	0.8	0.2	457.6	93.2	373.5	71.0
2F5	474	47.4	92.2	23.1	206.2	42.0	4.2	0.8
b12	509	50.9	375.9	94.2	1.0	0.2	260.4	49.5

The header row describes the input virus, either total virus for the first round capture (1000 ng/p24) or the collected unbound fraction following first round depletion with 4B3 (399 ng/p24), b12 (491 ng/p24) or 2F5 (526 ng/p24)

Italics indicate the values after first round capture
