Glass-based Arrays (G-Series)

Glass slide antibody arrays for high-sensitivity, multiplex protein profiling from small samples

RayBio G-Series glass slide antibody arrays print sandwich antibody pairs onto a slide the same size as a standard histology slide, read out via fluorescence for a wider dynamic range than membrane-based formats. You can screen dozens to hundreds of proteins from a single sample, with detection limits reaching the low pg/ml to ng/ml range across around four orders of magnitude. A biotinylated detection antibody cocktail and streptavidin-conjugated fluorophore give a semi-quantitative, relative fluorescence signal for each target, and a free slide-scanning and data-extraction service is available if you do not have a scanner. Panels cover human, mouse, and rat cytokines, chemokines, growth factors, and soluble receptors.

Pick by panel and scanner.

1. Panel size. Match to your study question.
2. Species. Human, mouse, rat coverage varies.
3. Scanner compatibility. Standard 532/635 nm microarray scanners.
4. Quantification. In-slide standard curves give absolute concentrations.
5. Sample volume. 30 to 100 microliters typical per replicate.
