The resDetect™ Universal Protein A Quick ELISA Kit (Boiling-free) can detect protein A or unnatural protein A variants within 2 hours, it is high sensitive and easy to operate because the sample processing has been changed from the original boiling method to adding denaturing reagents. The sample processing process has been shortened by one hour. Whether in upstream small-scale trials or downstream large-scale of antibody production processes, this kit can help you to accurate analysis of samples, monitor the protein A levels and ensure product quality.
The kit is developed for the detection of natural or structurally conserved recombinant forms of Protein A and a recombinant form of Protein A with very significant structural differences from natural Protein A such as MabSelect SuReTM in Bioprocess manufacturing applications. It is used as a tool to aid in optimal purification process development and in routine quality control of in-process streams as well as final product.
It is for research use only.
Find the expiration date on the outside packaging and do not use reagents past their expiration date.
The opened kit should be stored per components table. The shelf life is 30 days from the date of opening.

We have conducted interference effect test about frequently-used buffers, they have excellent buffer compatibility. For specific buffers, it is recommended that you verify recovery to determine the minimum dilution ratio.
Host cell protein (HCP 500 ng/mL) and host cell DNA (HCD 0.5 ng/mL) of HEK293, E.coli or CHO systems were added to human IgG1 (Bevacizumab, 1mg/mL) and human IgG4 (Toripalimab, 1mg/mL), respectively, which were higher than the usual quality standard limit. Then high, medium, and low concentrations of Protein A were added, respectively, and the ratio of Protein A recovery in the Protein A added samples without HCP and HCD was added as the specificity verification index. verification index.
