β-D-Glucose:oxygen 1-oxidoreductase, G.Od., GOx

Rapid isolation and purification of total RNA from cultured animal cells, tissue samples, blood, plasma, serum, bacteria, yeast, fungi, plants and viruses.

A simple, rapid, and cost effective method for isolating endotoxin-free plasmid DNA from recombinant E. coli cultures.

Sufficient for 100 colorimetric or fluorometric tests.

Fluorescein sodium salt has been used as a solute to study microvessel permeability. It has been used as a test molecule to study blood barrier penetration. Water soluble fluorescent dye used in permeability and vascular perfusion studies due to its small molecular radius. Sodium fluorescein is used as a fluorescent tracer to study blood-brain barrier (BBB) and blood-spinal cord barrier (BSCB) permeability in rodent mode…

siRNA ranking are listed in order of expected efficacy (1 being the best) as predicted by the Rosetta algorithm. All predesigned siRNA carry the Sigma-Aldrich guarantee. NM_005194 - human NM_024125 - rat NM_009883 - mouse

LiChrosolv hypergrade is accurately tested for LC-MS suitability, and meet all the requirements of modern LC-MS ionization methods (ESI/APCI - positive and negative mode). Thanks to their low level of ionic background and low ion suppression, LiChrosolv hypergrade solvents provide high reproducibility and high ionization efficiency. The packaging material has been improved to meet LC-MS quality requirements perfectly.

Casein from bovine milk is a phosphoprotein. There are four main types of Casein which make up approximately 80% of the total protein in bovine milk: α-s1 Casein, α-s2 Casein, β-Casein, and κ-Casein. Casein is proposed to be the main protective constituent in milk.

The GenElute™ RNA/DNA/Protein Purification Plus Kit provides a rapid method for the isolation and purification of total RNA, genomic DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, blood, bacteria, yeast, fungi or plants.

nanopowder, <200 nm particle size (BET), ≥97%, synthetic  

Nafion ™  is a perfluorosulfonic acid nafion resin that is majorly used as a strong solid acid (H 0  -12) with high thermal stability and chemical resistance.

Also known as androstanolone or DHT, 5α-Dihydrotestosterone is an androgen or male sex hormone that has been implicated in a broad range of disease from male pattern baldness to benign prostatic hyperplasia and prostate cancer. As an anabolic steroid, DHT has also been used as a performance-enhancing drug to promote muscle growth. This Certified Spiking Solution® is suitable for GC/MS and LC/MS applications from clinical and d…

PESTANAL ®  pesticide analytical standards are specifically designed for your routine analytics or screening tests.

The triglyceride and free glycerol kits are for the quantitative determination of glycerol, total triglycerides or free triglycerides.

1.0 mg/mL in methanol, ampule of 1 mL, certified reference material, Cerilliant®  

Duolink ® In Situ Detection Reagents Far Red contains all the necessary reagents to perform the amplification and detection of bound PLA ® probes. 

Phosphorus pentachloride is a light yellow colored phosphorous halide. It participates in the synthesis of thiazoline analogs.

For use to enrich for specific regions of chromatin that are immunoprecipitated with a specific antibody for a chromatin protein. Works with all eukaryotic cell types. Detection of the gene or promoter of interest in immunoprecipitated chromatin must be empirically determined by the researcher. Quantitative PCR detection is recommended.
