RayBiotech Life, Inc. products

Combining direct antigen-labeling technology with our vast library of array-validated antibodies, RayBiotech has created our largest antibody array to date: the Human L6000 Array. With the L-Series high density array platform, researchers can now detect up to 6000 proteins simultaneously, obtaining a broad, panoramic view of protein expression. Our newly expanded panel includes a wide variety of metabolic enzymes, structural proteins, epigenetic markers, neuroregulatory factors, in addition to our popular list of cytokines, growth factors, receptors, adipokines, proteases, and signaling proteins. Available on both glass slide and membrane formats, this array is ideally suited for biomarker discovery studies and exploratory screens.

Semi-Quantitative, Sandwich-Based, Membrane Antibody Arrays. The RayBio® Membrane-Based Antibody Arrays (C-Series) are tools for screening and comparing expression levels of many cytokines, growth factors, proteases, soluble receptors, and other proteins in a wide variety of sample types. The C-Series Arrays utilize the sandwich immunoassay principle, wherein a panel of capture antibodies is printed on a nitrocellulose membrane solid support (usualy 2.5 cm x 3 cm). The array membranes are processed similarly to a Western blot (chemiluminescent readout). Signals are then visualized on x-ray film or a digital image, allowing densitometry data collection and calculation of fold-changes for each detected protein. The entire procedure can be completed in 1 day, and is simple enough to permit even the novice researcher to successfully collect data with very few pitfalls and little or no optimization.
