Biological activity test kit Octet®

No sample purification or digestion required; reduces preparation time by up to 3 hours Screen for samples with desired sialylation levels – high, medium or low Combine titer data with sialic acid data for more informed decisions Glycosylation is considered among the most important post-translational modifications when developing new biologics. Having a significant impact on product performance and variability, glycosylation is a critical quality attribute (CQA) influencing product safety and efficacy. Protein glycosylation can affect isolation and purification steps (process consistency), pharmacokinetics (half-life) properties and in vitro stability (product shelf-life). Sialic acid content is especially important as it can impact the stability and clearance of a protein. The Sialic Acid (GlyS) Kit provides a rapid and convenient method for relative screening of terminal sialic acid content in crude or purified samples. Sialic acid data can be combined with titer data using Octet Data Analysis HT software version 11.1 or higher to funnel through samples that are high producers and have desirable sialic acid content.
