作者文章总结
• Development and validation of a reliable, robust and efficient assay to detect and quantifymacromolecules in vitro and in vivo during the early stage of a biotherapeutic agent discovery remain a major challenge for researchers, especially in the academia setting where resources can be limited.
• A simple (enrichment-free), highly sensitive and efficient immunoassay using a capillary-based western system to assess the in vitro stability and pharmacokinetic properties of propitious epitope-tagged recombinant proteins in vivo in mouse to support an early stage development of a lead therapeutic recombinant protein.
• The method validation results demonstrated satisfactory characteristics in specificity, linearity, accuracy and precision.
• This protocol avoids the need of laborious and costly customized monoclonal antibody as is typically essential for an ELISA or multistep enrichment process which are often indispensable when employing a liquid chromatography–mass spectrometry-based method.
• The protocol is capable of quantifying up to 25 samples at the dynamic concentration range from 5 to 200 ng/ml with an LLOQ of the target protein at 0.4 nM (20 ng/ml).
