Research Use Only

Background This spin-column type IgG antibody-purify kit consists of immobilized Protein A (Catalog Number: CSR-APK-10A) or Protein G (Catalog Number: CSR-APK-10G) on the solid phase of filter type monolithic silica with uniform continuous pores. Compared with conventional ones, this product can easily purify IgG antibodies in a shorter time (approximately 3 minutes). The column can be recycled up to 5 times without diminishing antibody binding capacity. Each can purify IgG antibodies up to 0.4 mg with Protein A and 0.3 mg with Protein G per column under more than 90% of recovery rate. 1: In case purified antibodies or culture supernatants are used, up to five replicates of the columns can be reused. However, if the sample contains a solid component such as protein in the serum, it may cause a clogging of the column, which may result in a decrease in the regeneration frequency and fluid permeability. Therefore, this product should be used after removal of the solid component by centrifugal removal or filter filtration. Composition Kit contains sufficient reagents for 60 individual purifications (approx. 3 runs per column) Features Easy-to-handle spin columns Fast purification process: IgG antibodies can be purified in aprox. 3 minutes! Column can be re-used (max. 5 times) References Hattori,et al. A small molecule compound with an indole moiety inhibits the main protease of SARS-CoV-2 and blocks virus replication.
