Aggregation, %4-SO₃ levels and the corresponding in vitro potency for the top three clones.

CAP256V2LS clone	Aggregation % (n = 4)	4-SO3% (n = 4)	%RP	Neutralization efficiency IC80
				A03349M1_VRC4A	Du156.12	MI369	SVA.MLV
198	5.7 ± 0.5	54.7 ± 5.3	70	0.093	0.019	0.014	> 50
344	4.9 ± 0.8	58.1 ± 1.8	84	0.059	0.012	0.010	> 50
386	2.6 ± 0.1	87.0 ± 0.3	99	0.025	0.009	0.007	> 50

(%RP, a single value from the curve, is normalized against an interim CAP256V2LS reference standard. Neutralization efficiency IC₈₀ is a single value derived from interpolation of 80% signal reduction on a 10 point serially diluted point curve fit via 5-PL non-regression analysis).
