Bovine Serum Albumin (BSA) is loaded onto an SDS-PAGE gel. The Precision Plus molecular weight marker was run in a separate lane on this gel. A calibration curve is generated based on migration distances of the fragments in the marker and this curve has a trendline of \( y= \) \( -1.73 x+5.46 \). The \( R_{1} \) of \( B S A \) was calculated to be \( 0.33 \). What is the molecular weight of BSA? d. \( 66 \mathrm{kDa} \) c. \( -1.03 \mathrm{kDa} \) b. \( 4.88 \mathrm{kDa} \) a. \( 77 \mathrm{kDa} \) \( e .51 \mathrm{kDa} \)
