Because of the popularity of cancer immunotherapy and monoclonal antibody drugs, biopharmaceuticals have entered the fast lane of technology iteration. While pursuing the upgrading of production capacity, biopharmaceuticals have made great efforts to improve the biological activity and process optimization of products. In addition, they have put forward higher requirements for the professionalization of various links in the industrial chain.
With a comprehensive cell, molecular and immune product line, Genetime Excell Bio co.ltd can provide high-quality imported fetal bovine serum, serum-free medium and other core reagents for cell culture and related products for the biopharmaceutical industry, as well as qPCR Mix, ELISA detection kit and other transcription and translation detection and identification tools.

applyIn the production and purification process of antibody products, Protein A affinity chromatography resin is a commonly used tool to separate and purify antibodies. However, during the antibody purification process, Protein A will fall off, causing antibody products contains Protein A, thus affecting the purity and potency of the product, causing major problems to the pharmaceutical industry. For example, the 2020 edition of the Chinese Pharmaceutical stipulates that the Protein A residue detected by enzyme-linked immunoassay for nimotuzumab injection should not be higher than 0.001% of the total protein, so the Protein A residue in biological products must be detected. Protein A includes natural Protein A, recombinant Protein A, and alkali-resistant recombinant Protein A which structure is significantly different from natural Protein A, such as GE’s MabSelect SuReTM Protein A. This product can quantitatively detect shed natural Protein A and recombinant Protein A, if you need detect alkaline-resistant recombinant Protein A, please choose our CRP00-302* series and CRP00-303* series kits. Please Attention! Before using this kit for the first time, it is recommended to complete a product suitability study to confirm whether there is interference in the sample matrix and the appropriate dilution conditions for sample detection.
