Made with high-purity reagents and are strictly quality controlled

Green-to-blue (A562nm), precise, detergent-compatible assay reagent to measure total protein concentration vs. protein standard.

Less hazardous and does not require methanol or acetic acid fixatives or destains

Ready-to-use reagent to reduce protein samples for protein gel electrophoresis

Made with high-purity reagents and are strictly quality controlled

Easily capture and affinity purify binding partners of GST-tagged fusion proteins with these glutathione (GSH) agarose beads and complete reagent set.

Calibrate LTQ Velos, LTQ Orbitrap and other mass spectrometers using a mixture of highly purified ionizable molecules designed for positive mode calibration.

Ready-to-use, water-soluble peroxidase substrate tablets that yield a measurable green end-product for use in ELISA methods.

Formulation: Protein expressed in E. coli. Purity: >95%. Format: Lyophilized.

Use for convenient and fast small-scale cleanup of proteins and other large biomolecules (>5000 M_r).  Cytiva Life Sciences™ PD SpinTrap™ G-25 Desalting Columns provide the option of running multiple samples in parallel.

Qdot™ 655 ITK™ Carboxyl Quantum Dots

Designed specifically for Western blots and protein sequencing. Immobilon™-FL PVDF Transfer Membranes are plain surfaced with 0.45μm pores and have lower background fluorescence than other membranes. Available in 10cm and 20cm squares and a 3.75m roll.

Combines exceptional photostability with bright and intense signals. Cytiva Cy3B Maleimides Mono-Reactive CyDye is a more selective method of antibody labeling that reduces the possibility of the label interfering with subsequent antibody-antigen reactions.

Ideal for molecular separation, protein binding studies, electrolyte removal, desalting

Horseradish peroxidase (HRP) substrates for ELISA that change from blue to yellow upon addition of a sulfuric or phosphoric acid stop solution.

Calibrate LTQ mass spectrometer instruments using a mixture of highly purified ionizable molecules designed for negative mode calibration.

For use with fluorescence microscopy

Ideal for molecular separation, protein binding studies, electrolyte removal, desalting

Fibronectin Human Protein, Plasma

Streptavidin from Streptomyces avidinii conjugated to highly purified horseradish peroxidase (HRP)

Proprietary reagent that maintains proteins in a reduced state during protein gel electrophoresis

Use with Novex Tris-Glycine Gels

Ultra-sensitive enhanced chemiluminescent (ECL) HRP substrate for low-femtogram-level detection by Western blot analysis.

Effectively screen colonies with X-Gal, an inert chromogenic substrate for beta-galactosidase which hydrolyzes X-Gal, forming an intense blue precipitate.

Biotinylate protein amines (e.g., lysines) with our shortest (13.5A), water-soluble, NHS-ester biotinylation reagent for antibody or cell-surface labeling.

HABA dye reagent and biotinylated protein standard for convenient colorimetric determination of biotinylation levels in antibodies and other proteins.
