Figure 2a – Effect of Varying Primary Antibody
Concentration in Antibody Solution with 2% Milk:
Bolded
concentrations indicate the dilution of the primary antibody concentration.
A.
Blocked in 5% milk, 1.0 microgram/mL
primary antibody in 2% milk and 0.15 M NaCl.
B.
Blocked in 5% milk, 0.3 microgram/mL
primary antibody in 2% milk and 0.15 M NaCl.
C.
Blocked in 5% milk, 0.1 microgram/mL
primary antibody in 2% milk and 0.15 M NaCl.
Figure 2b – Effect of Varying Primary Antibody Concentration in
Antibody Solution with 5% Milk:
In addition to the dilution of the primary antibody concentration (bolded), the milk concentration in the Antibody Solution was
also increased.
D.
Blocked in 5% milk, 1.0 microgram/mL
primary antibody in 5% milk and 0.15 M NaCl.
E.
Blocked in 5% milk, 0.3 microgram/mL
primary antibody in 5% milk and 0.15 M NaCl.
F.
Blocked in 5% milk, 0.1 microgram/mL
primary antibody in 5% milk and 0.15 M NaCl.
