Table 3.
One-to-one Langmuir fitting parameters to anti-biotin reactions with surface biotin-bovine serum albumin and biotin-polyvinyl alcohol conjugates. The loading was specified by the molar ratio of biotin to bovine serum albumin (40×, 20×, 10×, and 5×) or the percentage of biotin to polyvinyl alcohol (4%, 2%, and 1%).[28]
