This study explores the specificity of affinity purification using FP-TAMRA labeled urine and anti-HIV antibody-conjugated beads. Results show that the beads did not enrich FP-TAMRA labeled bands. Key materials include the FP-TAMRA labeled starting material, eluted protein from the anti-HIV column, and total protein analyses. The evaluation also highlights the use of serine hydrolase activity-based protein profiling (ABPP) and the Sypro Ruby staining method for total protein quantification, providing insights into the efficiency of antibody-based enrichment techniques.
