Protein Quantification Products & Reviews

The Gyrolab® 2G Generic PK Kit enables high sensitivity quantitation of intact human IgG (IgG1, IgG2, IgG4 subtypes) in preclinical matrices

For your proteomics, metabolomics, or lipidomics research initiatives, Waters TransOmics Platform Solution for Proteomics, and/or for Metabolomics and Lipidomics, streamlines the entire omics workflow, enhances productivity—from sample preparation to publication of results.With Waters, watch your large, biologically significant, multi-run LC/MS datasets turn into meaningful, publication-ready reports.

Highly sensitive, fluorescence-based quantitation of purified proteins.

Easily label SNAP-tag®, CLIP-tag™, HaloTag®, or other ligands with fluorescent dyes, no purification needed. Cell membrane-permeant and impermeant dye options for intracellular or surface targets.

Label 5-50 ug of VHH (also known as Nanobodies®) containing a single free cysteine with Biotium’s bright and photostable CF® Dyes, with no purification after labeling.

Label your IgG antibody with one of our superior CF® Dyes in as little as 15 minutes without a purification step. Labeling tolerates many common buffer components including BSA and ascites.

Label your IgM antibody with one of our superior CF® Dyes in 15-30 minutes without a purification step.

DSL binds to (beta-1,4) linked N-acetylglucosamine oligomers, preferring chitobiose or chitotriose over single N-acetylglucosamine residues. Biotium offers DSL conjugated to biotin and a selection of 6 bright and photostable CF® Dyes.

A lectin labeled with our superior fluorescent CF® dyes is an effective and widely used cell surface stain for yeast, fungi, and mammalian cells.

These kits allow optimal labeling of single-chain nanobodies with CF® dyes or biotin in 30 minutes without a purification step.

Label your antibody with one of our CF® Dyes specialized for STORM super-resolution microscopy. Labeling takes just 30 minutes without a purification step, and yields an antibody conjugate with a low degree of labeling optimal for STORM.

Target Sufficiency® is the ability of a target system to respond to a therapeutic. It reflects the abundance and forms of the drug target protein, as well as other key system proteins that connect the target to disease phenotypes and enable response. Assessment of the target system requires an analysis platform that can simultaneously capture multiple precise protein measurements.

Our Protein Binding Platform assesses drug-protein interactions using equilibrium dialysis and ultracentrifugation methods to determine unbound fractions and distribution in biological samples including plasma, blood, tissues, and cells. This essential ADME service evaluates reversible drug transfer between compartments, providing insights into pharmacokinetics, bioavailability, and potential interactions.

In diagnosis of Rheumatoid Arthritis (RA), the measurement of anti-CCP is integral. People who test positive for Anti-CCP, are very likely to develop or have already developed RA, but not all who have RA, necessarily develop anti-CCP. Early detection of RA is crucial for reducing tissue damage.

The Succinate-Glo™ JmjC Demethylase/Hydroxylase Assay is a bioluminescent assay for detecting the activity of JumonjiC (JmjC) histone demethylases and many Fe(II)/α-ketoglutarate-dependent dioxygenases that use α-ketoglutarate as substrate and release succinate as a product.

The H2A.X Phosphorylation Assay Kit (Flow cytometry) is a cell based assay formatted for flow cytometric detection of levels of phosphorylated Histone H2A.X. Cells are cultured in microplates, treated with agents that induce DNA damage or apoptosis, which stimulates H2A.X phosphorylation. Cells are then fixed and permeabilized in preparation for staining and detection. Histone H2A.X phosphorylated at serine 139 is detected by…

The TRAPeze® Telomerase Detection Kit is a highly sensitive in vitro assay system for detecting telomerase activity. The assay is a one-buffer, two-enzyme, system utilizing PCR to enhance the sensitivity of telomerase detection in small samples.
