Use for convenient and fast small-scale cleanup of proteins and other large biomolecules (>5000 M_r).  GE Healthcare 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. GE Healthcare 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

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

Fibronectin Human Protein, Plasma

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

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.
