The Fluorescent Protein Hub

Fluorescent proteins (FPs) have revolutionized molecular and cellular biology, serving as essential reporter tags for visualizing gene expression, protein localization, and intracellular dynamics in living cells. From the classic Green Fluorescent Protein (GFP) derived from Aequorea victoria to highly engineered monomeric red derivatives like mScarlet and mCherry, selecting the correct FP is critical for avoiding spectral overlap and ensuring vivid imaging.

At Biorbyt, we provide a comprehensive catalog of highly specific primary and secondary antibodies validated for the detection, immunoprecipitation, and Western Blot analysis of widely used fluorescent proteins. Explore our technical resources, selection guides, and specialized reagents below to optimize your flow cytometry and fluorescence microscopy assays.
