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…

The Fused-Core ® particle technology behind Ascentis ® Express columns delivers maximum speed and efficiency on both HPLC and UHPLC systems. The novel superficially porous silica particles (SPP) are available in three different particle sizes and two different pore sizes for optimal suitability from micro over UHPLC and HPLC to semi-preparative use.

A pure water solution, integrating Elix ® technology for your essential needs

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…

If you want precision and reliable measurements combined with ease of use, Merck offers you a range of certified, ready-to-use Certipur® buffer solutions with exact reference pH values safely packed in sealed sachets. Preparation effort is thus reduced to a minimum: Just open the sachet and start calibrating. The buffer solutions come in small and handy single-use quantities (30 ml) and are always fresh, without residues and…

standard, 12-port model

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

Monolithic silica-based Chromolith® HPLC columns allow rapid separations at very low column backpressure with high matrix tolerance and extended column lifetime, thus making them ideal products for high throughput and cost-efficient analyses of matrix-rich samples. 

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.

The Guava® Caspase 3/7 and 8 Assays employ a FLICA (Fluorescent Labeled Inhibitor of Caspases) reagent that specifically identifies active caspase 3 and 7 molecules or caspase 8 molecules. Non-cytotoxic, cell permeant dyes elimiate lysis and permeabilization procedures. Each FLICA is comprised of three subunits: A caspase-specific amino acid inhibitor containing a recognition sequence for caspase 3/7 (DEVD) or caspase 8 (LETD)…

The SNAP i.d. Protein Detection System revolutionizes the quality of your blots every time — in record time! Unlike conventional Western blotting, where diffusion is the primary means of reagent transport, the SNAP i.d. system applies a vacuum to actively drive reagents through the membrane. This novel method allows you to optimize your blotting conditions in record time for maximum results. The SNAP i.d. system minimizes over…
