Thermo Scientific™ Spectra™ Multicolor Broad Range Protein Ladder
Thermo Scientific™ Spectra Multicolor Broad Range Protein Ladder is a 4-color protein standard containing 10 prestained proteins (10 to 260 kDa) for use as size standards in gel electrophoresis and Western blotting.
Thermo Scientific™ Halt™ Phosphatase Inhibitor Single-Use Cocktail
Stabilize serine, threonine and tyrosine phosphorylation of proteins in cells and tissues with this cocktail of phosphatase inhibitors.
Thermo Scientific™ Spectra™ Multicolor Low Range Protein Ladder
A mixture of six proteins and synthetic peptides (1.7 to 40kDa) for use as size standards for peptides and small proteins in gel electrophoresis and Western blotting.
Thermo Scientific™ Pierce™ Protein-Free Blocking Buffer
Pierce Protein-Free Blocking Buffer is a non-protein compound that provides effective blocking for membrane-based and plate-based protein detection methods, resulting in extremely low background.
Thermo Scientific™ Slide-A-Lyzer™ G3 Dialysis Cassettes, 20K MWCO
Thermo Scientific Slide-A-Lyzer™ G3 Dialysis Cassettes facilitate the rapid and trouble-free dialysis of sample volumes from 0.5 to 125 mL. Unlike standard flat tubing, these innovative devices do not require knots or clips that can lead to leaking and sample loss.
Thermo Scientific™ Slide-A-Lyzer™ G3 Dialysis Cassettes, 3.5K MWCO
Thermo Scientific Slide-A-Lyzer™ G3 Dialysis Cassettes facilitate the rapid and trouble-free dialysis of sample volumes from 0.5 to 125 mL. Unlike standard flat tubing, these innovative devices do not require knots or clips that can lead to leaking and sample loss.
Thermo Scientific™ Spectra™ Multicolor High Range Protein Ladder
A mixture of eight blue-, green- and orange-stained proteins (40 to 300kDa) for use as size standards for high MW proteins in gel electrophoresis and Western blotting.
Thermo Scientific™ Slide-A-Lyzer™ G3 Dialysis Cassettes, 10K MWCO
Thermo Scientific Slide-A-Lyzer™ G3 Dialysis Cassettes facilitate the rapid and trouble-free dialysis of sample volumes from 0.5 to 125 mL. Unlike standard flat tubing, these innovative devices do not require knots or clips that can lead to leaking and sample loss.
Thermo Scientific™ Subcellular Protein Fractionation Kit for Cultured Cells
Enrich for cultured cell-specific cytoplasmic, membrane, nuclear soluble, chromatin-bound and cytoskeletal proteins in less than 3 hours.
Thermo Scientific™ Halt™ Protease and Phosphatase Inhibitor Cocktail (100X)
Prevent protein degradation and stabilize phosphorylation with this all-in-one cocktail of protease and phosphatase inhibitors.
Invitrogen™ Bolt™ Bis-Tris Plus Mini Protein Gels, 8%, 1.0 mm, WedgeWell™ format
Invitrogen Bolt Bis-Tris Plus gels are precast polyacrylamide gels designed for optimal separation of a wide range of protein sizes under denaturing conditions.
Thermo Scientific™ Halt™ Protease and Phosphatase Inhibitor Cocktail, EDTA-free (100X)
Prevent protein degradation and stabilize phosphorylation with this all-in-one cocktail of protease and phosphatase inhibitors.
Invitrogen™ Mini Gel Tank and Blot Module Set
Provides all of the necessary devices for protein separation and Western blotting using Novex™ gels, NuPAGE™ gels, and Bolt™ Bis-Tris Plus gels
Invitrogen™ Bolt™ Bis-Tris Plus Mini Protein Gels, 10%, 1.0 mm, WedgeWell™ format
Similar to NuPAGE™ Bis-Tris gels, Bolt™ Bis-Tris Plus gels are designed to deliver consistent gel performance and provide a neutral pH environment that minimizes protein modifications.
Thermo Scientific™ Restore™ Western Blot Stripping Buffer
Safely and effectively remove primary and secondary antibodies from nitrocellulose and PVDF membranes to allow chemiluminescent Western blots to be reprobed.
