Sigma Aldrich Fine Chemicals Biosciences EZMTT High Sensitivity Cel
NAD/NADH and NADP/NADPH are important biological cofactors foroxidoreductase enzymes that arefundamental for various biological processes such as energy metabolism mitochondrial function oxidative stress immunological functions and cell death. Hence the oxidoreductase enzymes are used as indicators of metabolic activity of cells.Traditional tetrazolium salts such as MTT react with NAD(P)H-dependent cellular oxidoreductase enzymes to produce an insoluble formazan which requires solubilization and have lower sensitivity. Moreover they cannot reliably detect cell viability in low density cultures such as primary cell cultures. EZMTT viability assay SOLUTIONon is based on a novel monosulfonated tetrazolium salt 2-(3-(2-methoxy-4-nitrophenyl)-2-(4-nitrophenyl)-2H-tetrazol-3-ium-5-yl) benzenesulfonate sodium salt (EZMTT). The EZMTT reagents provided high quality and reproducible detection for oxidoreductase enzymes indicators of cellular metabolic activity. Upon reacting with meta

Sigma Aldrich Fine Chemicals Biosciences HyStemR HP Cell Culture Sc
The HyStem(R)-HP Cell Culture Scaffold Kit provides an excellent starting point for optimizing the matrix for stem cell culture where slowly released growth factors are crucial in re-creating a stem cell niche. To affect specific cell performance growth factors or ECM proteins may be added to the HyStem-HP hydrogel. Unlike animal-derived ECM products this kit contains three fully chemically defined components which are nonimmunogenicHyStem(R)-HP - a thiol-modified hyaluronan (a major constituent of native ECM) carboxymethyl hyaluronic acid-thiopropanoyl hydrazide (CMHA-S CMHA-DTPH carboxymethyl hyaluronic acid-DTPH) with heparinthiopropanoyl hydrazide (HP-DTPH). HyStem-HP (CMHA-DTPH with HP-DTPH) contains 99.7 wt% CMHA-DTPH and 0.3 wt% HP-DTPH.Gelin-S(TM) - a thiol-modified gelatin (denatured collagen) carboxymethyl gelatin-thiopropanoyl hydrazide (GTN-DTPH carboxymethyl gelatin-DTPH)Extralink(R) - a thiol-reactive crosslinker polyethylene glycol diacrylate (MW
Med Vet International Dynarex Sterile Dynaginate Calcium Alginate Dressing, 4.25" X 4.25", 120/Case
Calcium Alginate Dressings contours to wound bed and changes to a fibrous gel when in contact with wound exudate, creating an optimal moist wound environment important to healing. Changes to a fibrous gel when in contact with wound exudate, creating a moist wound environment. Contours to the wound bed and will not adhere to the wound upon removal. High absorbency dressing used for heavily exuding wounds. Primary dressing ideal for the management of partial and full thickness wounds at stages 3 or 4.
Hach Company Replacement Silicone Wiper for Mechanical Cleaning Unit - For TU5300sc and TU5400sc Turbidimeters
