Protein Analysis

Enhance your workflow with protein stability and protein quantitation assays built for exceptional sensitivity, reproducibility, and ease of use. Choose protein concentration assays with highly linear response, minimal variability, and stable fluorescent signal, or run rapid, cost-effective protein stability assays on standard qPCR systems, even in the presence of detergents and additives.

AccuOrange™ Protein Quantitation Kit

Quantify purified proteins with precision in a 96-well format using a highly linear, stable, fluorescence-based assay with a detection range of 0.1-15 µg/mL protein.

GloMelt™ 2.0 Thermal Shift Protein Stability Kit

Updated GloMelt™ assay featuring a therapeutically relevant Recombinant Monoclonal Mouse IgG1 control, delivering higher signal and sharper melt peaks for robust validation.

GloMelt™ Thermal Shift Protein Stability Kit

Original fluorescence-based stability assay optimized for high-throughput formats, low volumes, and low protein concentrations.
