Routine Clinical Adoption of Immunoassay Multiplexing, Whether Microarray or Cytometric Bead Array, Is Still Several Years Away Due to Operational Entrenchment

An objective look at immunoassay multiplexing, where it stands today and contrasted to the standard ELISA was authored recently by Dr. Lucy Fairclough et al. The discussion argued the efficacy of multiplexing as well as the pros and cons of present methods available.Commercial availability of multiplex immunoassays for life science discovery research is rapidly expanding … Continued

Beating Background Fluorescence on Nitrocellulose Film-Slides

Near Infrared Detection with Porous Nitrocellulose Films Improves Sensitivity for Protein Arrays. Despite some clear performance advantages of porous nitrocellulose Film-Slides for protein arrays, one objection to their use is the inherent fluorescence background detected on most scanners when using popular organic dyes with visible emission wavelengths (500-650 nm). However, fluorescence detection in near infrared … Continued

Immunoassays: Protein Arrays vs. ELISA and Westerns

Studies of biological systems have expanded beyond the ‘one gene, one protein’ paradigm to the field of proteomics, or studying large numbers of proteins that act in a concert of complex biological systems. Thus in the post-genome era, technology has been driven to deliver multiplex assays that allow us to monitor multiple proteins in parallel, … Continued
