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

Made with high-purity reagents and are strictly quality controlled

Allows the closest estimation of molecular weight of your sample protein over a wide molecular weight range

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.

Mixture of 10 blue-, orange- and green-stained proteins (10 to 180kDa) used as size standards in protein electrophoresis (SDS-PAGE) and Western blotting.

Run these markers in parallel with the experimental samples on isoelectric focusing gels. Cytiva Life Sciences™ pI Markers are lyophilized mixtures of stable, salt-free, highly purified proteins.

Block mammalian tissue samples for immunohistochemistry (IHC) and samples for other methods with steelhead salmon serum in PBS.

Block membranes, plates and other samples with these ready-to-use PBS solutions of purified casein for Western blot, ELISA, and other detection methods.

Mixture of 9 blue-, orange- and green-stained proteins (10 to 250kDa) used as size standards in protein electrophoresis (SDS-PAGE) and Western blotting.

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

Can be used to fix cells prior to permeabilization with the Permeabilization Buffer (cat. 00-8333) when performing intracellular staining of antigens located in the cytoplasm and secretory pathway, such as cytokines, chemokines and growth factors.

Can be used to fix and permeabilize cells prior to performing intracellular staining of cytokines and other cytoplasmic and/or nuclear antigens.

Designed for accurate, easy, and convenient molecular weight estimation of a wide range of molecular weight proteins during SDS-PAGE and Western blotting

A mixture of six blue-stained natural proteins (20 to 120kDa) for use as size standards in protein electrophoresis (SDS-PAGE).

For use with all sandwich ELISAs which utilize Horseradish Peroxidase (HRP) as detecting enzyme

Clear, self-sticking sealing tape for standard microplates.

Stain proteins in 1D and 2D gels with this rapid, ultra-sensitive and versatile silver stain system that yields consistent and reliable results.

Stop TMB-based ELISA detection with this 0.16M sulfuric acid for use with the ELISA substrate 3,3',5,5' - tetramethylbenzidine (TMB).

Allows you to easily visualize protein molecular weight ranges during electrophoresis and quickly evaluate Western transfer efficiency

Invitrogen Bolt Bis-Tris Plus gels are precast polyacrylamide gels designed for optimal separation of a wide range of protein sizes under denaturing conditions.

Invitrogen Bolt Bis-Tris Plus gels are precast polyacrylamide gels designed for optimal separation of a wide range of protein sizes under denaturing conditions. Bolt gels are ideal for western blot transfer and analysis, and any other techniques where protein integrity is crucial.

Optimized for use with Bolt™ Bis-Tris Plus gels, and are available in a variety of formats

Made with high-purity reagents and are strictly quality controlled.

Quickly and easily run up to two Novex 8 x 8cm minigels, leak-free without any clamps or grease

An enhanced chemiluminescent (ECL) horseradish peroxidase (HRP) substrate that enables picogram- to high femtogram-level protein detection by western blot analysis

For use in BD OptEIA™ ELISA sets. Substrate Reagent A, which is clear and colorless, contains hydrogen peroxide. Substrate Reagent B is colorless to a very light amber solution containing 3,3′, 5,5′ tetramethylbenzidine (TMB) in an organic solvent.

Ready-to-use blue TMB peroxidase (HRP) substrate specially formulated for chromogenic detection in Western blot and IHC experiments.

Preserve diluted (1-1,000ng/mL) HRP conjugates for more than six months at room temperature without significant loss of activity using Guardian Peroxidase Conjugate Stabilizer/Diluent.
