Made with high-purity reagents and are strictly quality controlled

Used to prepare protein samples for denaturing gel electrophoresis with NuPAGE™ Novex™ gels. Invitrogen™ Novex™ NuPAGE™ LDS Sample Buffer (4X) contains lithium dodecyl sulfate, pH 8.4, which allows for maximum activity of the reducing agent.

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 0.45 μm pores and have lower background fluorescence than other membranes. Available in 10 and 20 cm squares and a 3.75 m 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.

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

Fibronectin Human Protein, Plasma

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

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

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

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

Use with Novex Tris-Glycine Gels

Purified recombinant streptavidin enables detection of biotinylated antibodies and other probes in a variety of standard assay methods including western blotting, ELISA, immunohistochemistry, and fluorescence imaging.

IANBD Amide (N,N'-Dimethyl-N-(Iodoacetyl)-N'-(7-Nitrobenz-2-Oxa-1,3-Diazol-4-yl)Ethylenediamine)

Efficiently reduce protein disulfide bonds with this stable, odorless, 0.5M solution of TCEP reducing agent that is ideal for making reducing SDS-PAGE sample buffers.

Alexa Fluor™ 647 alkyne, triethylammonium salt

Perform sample buffer exchange with these 10,000-MW cut-off (MWCO) disposable polypropylene cups with integrated, low-binding membranes.

Analyze protein expression by mass spectrometry using these media or additives for stable isotope labeling with amino acids in cell culture (SILAC).
