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

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.

Thermo Scientific Fish Serum Blocking Buffer is steelhead salmon serum in PBS that is especially useful as a blocking agent in immunohistochemistry (IHC) and other detection methods involving mammalian samples.

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

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

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

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

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.

Uncoated ELISA Kit

Thermo Scientific™ Pierce TMB ELISA Substrates detect horseradish peroxidase (HRP) activity, yielding a blue color (Amax = 370 nm and 652 nm) that changes to yellow (Amax = 450 nm) upon addition of a sulfuric or phosphoric acid stop solution.

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.

Sustainable packaging

Alexa Fluor™ 488 streptavidin comprises a biotin-binding protein (streptavidin) covalently attached to a fluorescent label (Alexa Fluor™ dye).

SuperBlock Blocking Buffer is an optimized solution containing a single purified glycoprotein that provides incredibly fast and effective blocking for ELISA, IHC, and western blot analysis.

For quantitative detection of human IgA.

May be used as a substrate for horseradish peroxidase (HRP) in ELISAs

Alexa Fluor™ 647 streptavidin comprises a biotin-binding protein (streptavidin) covalently attached to a fluorescent label (Alexa Fluor™ dye).

Contains the NativePAGE Running Buffer (20X)

A solution used to solubilize native protein samples prior to use with the NativePAGE Gel System

Formulated for separation of proteins, in their denatured state, on Novex Tris-Glycine gels

Specifically measures the bioactive, heterodimeric form of IL-12, p70, without interference by p40 monomer, homodimer, or IL-23 (p19/p40). Engineered for accurate and precise measurement of human IL-12 p70 protein levels from samples including serum, plasma, and cell culture supernatants.

Ultra Streptavidin-HRP

Matched Antibody Pair

Optimized for the transfer of proteins from Bolt Bis-Tris Plus gels to membranes for western blotting

Prepare DNA markers and samples for loading on agarose or polyacrylamide gels with Thermo Scientific™ 6X DNA Loading Dye.

Matched Antibody Pair

HRP substrate optimized to generate an intense light signal and provide exception performance in luminometer-based assays.

Standard (sterile-filtered)

Add to samples prepared with the NativePAGE Sample Buffer and detergents (10% DMM or 5% Digitonin) just prior to applying the samples to NativePAGE gels
