Protein Quantitation Kits Products & Reviews

Bio-Rad offers four colorimetric protein assay kits for the measurement of protein levels using modifications of the Bradford and Lowry assay method. Disposable standard and semimicro plastic cuvettes ideal for these protein assays are also available.

Pierce LAL Chromogenic Endotoxin Quantitation Kit measures the amount of endotoxin in a protein, peptide, or antibody sample using the Limulus Amebocyte Lysate (LAL) assay.

Elastin impregnated with Congo red dye.

This reagent kit is intended for the “In Vitro “ quantitative determination of Potassium in Serum.

The Agilent Protein 80 kits provide a reliable way to assess protein concentration, identity, and purity. It eliminates handling of SDS-PAGE slab gels, staining or imaging steps.

Quantitate neutralizing antibodies against SARS-CoV-2 variants using the Bio-Plex Pro Human SARS-CoV-2 Variant Neutralization Antibody 11-Plex Panel

High-throughput sialylation screening for expediting the clone selection process

The host cell protein (HCP) ELISA detection kits  allow you to detect the presence of host cell protein impurities in your therapeutic at any phase of your product development

The FRETWorks™ S•Tag™ Assay is a FRET-based method that enables extremely sensitive detection of S•Tag fusion proteins in minutes with a homogeneous format.

The 384 well format kit is a newer version of the tried and true non-radiographic HDAC assay. As in the previous kit, samples are first incubated with the HDAC Assay substrate, allowing deacetylation of the fluorometric substrate. After incubation, the activator solution is added, and releases a fluorophore from the deacetylated substrate or standard. The sample is then put into a microplate reader and fluorescence (i.e free/c…
