The accurate, rapid and high-throughput measurement of immunoglobulin G (IgG) is essential in the development and subsequent manufacture of therapeutic antibodies.

However, with some IgG measurement methods—such as ELISA and Protein A HPLC—it may take hours to obtain results due to tedious sample prep and the need for multiple reagents. And when you’re processing hundreds or thousands of clones to generate a commercially viable cell line, those hours add up and add unnecessary complexity to your workflow.

With the Valita Titer assay, there’s no sample prep, additional reagents or wash required. Because of that, you’ll be able to prepare and measure a full 96- or 384-well plate in as little as 15 minutes.

Available in 96- and 384-well plate formats, and in two detection range formats—2.5 – 100 mg/L and 100 -2000 mg/L— the Valita Titer assay enables rapid, high-throughput IgG quantification directly from crude cell culture samples. The charts below compare IgG quantification in crude culture samples using the Valita Titer assay, biolayer interferometry (BLI), Protein A HPLC and ELISA.
