High Productivity and Process Economy in GxP Applications with the Octet™ Platform

Using the label-free optical technique of Bio-Layer Interferometry (BLI), the Octet platform provides real-time analysis of molecular interactions. It relies on the robust and easy-to-use Dip and Read™ format, which provides faster time to results relative to technologies like ELISA and SPR. It also operates in a fluidics-free format, thereby minimizing the complexity in analyte detection by fluidics-based technologies like SPR. It provides high-throughput analysis, with the option of analyzing to 96 samples simultaneously, thereby increasing analytical productivity. It has…

High-Throughput Sialylation Screening on an Octet Label-Free Instrument: Expediting Clone Selection in Cell Line Development

A high-throughput method for relative screening of terminal sialic acid content was developed on the Octet platform to expedite cell line development. The method is based on the use of ForteBio’s sialic acid (GlyS) kit to bind sialic acid on glycoproteins. The GlyS kit can screen specifically the sialylation levels of secreted proteins in crude cell culture samples and does not require purified samples. Using this method, 96 crude cell culture samples can be screened for sialylation in 60 minutes…
