Protein Quantification Products & Reviews

The Gyrolab® Protein A Kit for MabSelect SuRe Ligand enables rapid detection of resin ligands present in antibody preparation samples after Protein A purification

The Gyrolab® Generic PK Kit enables broad selectivity for quantification of intact human IgG (IgG1, IgG2, IgG4 subtypes) in preclinical matrices

Gyrolab® Assay Toolbox with 1000 nL sample volume for development of HCP assays with the components of ready-to-use HCP Kits.

Gyrolab Mixing CD 96 is recommended when applications require a pre-treatment step, e.g., acid dissociation prior to analysis of anti-drug antibodies. 96 datapoints.

Gyrolab huIgG Kit – Low Titer is a ready-to-use Gyrolab kit for determination of human monoclonal antibody (mAb) titers up to 20 µg/mL.

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

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.

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.

The His-Tag Protein Quantification Kit extends the Amperia™ Protein Quantification System for direct, tag-specific measurement of His-tagged recombinant proteins. Using a premix competition format with GenScript’s THE™ His Tag Monoclonal Antibody, the kit delivers accurate, reproducible results across both crude lysates and purified samples, with up to 80 tests per kit.

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.

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.

BRET-Based Assays to Detect Protein:Protein Interactions in Live Cells

Recombinant monoclonal antibody to ENG. It is a human monoclonal antibody that can be potentially used in the treatment of Hepatocellular Carcinoma, Gestational Trophoblastic Neoplasia, Choriocarcinoma, Placental Site Trophoblastic Tumor, Epithelioid Trophoblastic Tumor, Adult Solid Tumor, Advanced Soft Tissue Sarcoma, Metastatic Breast Cancer, Solid Tumors, Lung Cancer...

This product is a recombinant Human antibody that recognizes CRCP. The antibody was purified by affinity chromatography.

This product is a Human antibody that recognizes Human HLA-A*11:01.

This product is a Mouse antibody that recognizes Human Fc P329G LALA.

Recombinant monoclonal antibody to 4-1BB. This anti-4-1BB antibody is a fully human IgG4 monoclonal antibody targeting the CD137 receptor. It specifically binds to and activates CD137-expressing immune cells, stimulating an immune response, in particular a cytotoxic T cell response, against tumor cells.
