Biotech diagnostics developer Proteintech has introduced new magnetic agarose format of Conjugation CleanAb Kits for efficient antibody cleanup after conjugation in life science labs. Users can remove excess oligonucleotides or small molecule dyes with excellent antibody recovery and gentle elution at pH 7.5, supporting both post-conjugation purification and on-bead conjugation workflows.
CleanAb beads demonstrate superior performance across three critical parameters — binding affinity, elution conditions and recovery yield, says the company. The beads demonstrate high and consistent affinity and capacity, as evidenced by the absence of conjugated IgG in the flowthrough fraction. The enhanced binding capacity and consistent affinity towards all IgG subtypes not only increase yield but also improve reproducibility, ensuring consistent purification. The beads deliver high recovery rates of 60 – 90%, translating to significantly less product loss compared to other options.
