Figure 4. Hetero-oilgomerization of βB1 with βA3 as a function of time. βB1 was mixed with either βA3 WT (open circles) or βA3 DM (closed
circles) and incubated at 37 °C from 0-300 min and then subjected to SEC-MALS. The relative amount of complex was determined
from the peak area. Formation of the βB1:βA3 DM complex was slower than formation of the βB1:βA3 WT complex. Arrow indicates
90 min time point showing 40 % difference between WT and DM.
