Spectrophotometric colorimeters, PFXi 950 series, Lovibond®

Dodavatel: Lovibond Tintometer
Popis: Two spectrophotometric colorimeters that each include several of the popular scales that meet the requirements of objective colour analysis of oils, chemicals, fuels and other transparent products. The PFX<i>i </i>950 instruments are rugged colorimeters with fabricated steel housings, which function equally as QC instruments within the laboratory or on 24-hour operation in a production environment. The accuracy and repeatability of the colour data provided by these colorimeters ensures consistency in colour measurement, giving processors the confidence needed to make important decisions regarding raw materials and refining operations.

Anti-FBN1 Rabbit Polyclonal Antibody

Katalogové číslo: (PRSI28-762)
Dodavatel: ProSci Inc.
Popis: FBN1 is a member of the fibrillin family. FBN1 is a large, extracellular matrix glycoprotein that serve as a structural component of 10-12 nm calcium-binding microfibrils. These microfibrils provide force bearing structural support in elastic and nonelastic connective tissue throughout the body. Mutations in this gene are associated with Marfan syndrome, isolated ectopia lentis, autosomal dominant Weill-Marchesani syndrome, MASS syndrome, and Shprintzen-Goldberg craniosynostosis syndrome.

HPLC columns, preparative scale, Chromolith® Prep

Dodavatel: Merck
Popis: Chromolith® Prep monolithic stationary phases are new ultrapure silica phases which gain their special properties from a bimodal pore structure. This structure is a property of the new 'Sol-Gel' technology and consists of macropores and mesopores. The mesopores with an average diameter of 12 nm, form the fine porous structure of the column interior and create a very large surface area on which adsorption of the target compounds occurs.

Fluorescent β-Galactosidase assay kit

Katalogové číslo: (786-651)
Dodavatel: G-Biosciences
Popis: β-Galactosidase assay is for determining the β-galactosidase activity in the lysates of cells transfected with a β-galactosidase expression construct. It uses chlorophenol red-β-D-galactopyranoside (CPRG), which is up to 10 times more sensitive than the classic O-nitrophenyl-β-D-galactopyranoside (ONPG) β-Galactosidase assays. This increased sensitivity makes it simpler to measure β-galactosidase activity in cells that are difficult to transfect or have low β-galactosidase activity expression. β-Galactosidase activity is measured using a spectrophotometer or a microplate reader to determine the amount of substrate converted at 570 to 595 nm.

Anti-GFAP Chicken Polyclonal Antibody

Katalogové číslo: (PRSI50-268)
Dodavatel: ProSci Inc.
Popis: Glial Fibrillary Acidic Protein (GFAP) was discovered by Amico Bignami and co-workers as a major fibrous protein of multiple sclerosis plaques. It was subsequently found to be a member of the 10 nm or intermediate filament (IF) family, specifically the IF family Class III, which also includes peripherin, desmin and vimentin. GFAP is strongly and specifically expressed in astrocytes and certain other astroglia in the CNS, in satellite cells, peripheral ganglia, and in non-myelinating Schwann cells in peripheral nerves. In many damage and disease states GFAP expression is heavily upregulated in astrocytes. In addition, neural stem cells frequently strongly express GFAP. Point mutations in the protein coding region of the GFAP gene lead to Alexander disease which is characterized by the presence of abnormal astrocytes containing GFAP protein aggregates known as Rosenthal fibers.

Nikotinamid-adenindinukleotid (oxidovaná forma) ≥98%, white powder cell culture reagent

Dodavatel: MP Biomedicals
Popis: Storage: -20°C, desiccate
This is an ultrapure NAD, chromatographically purified to remove trace inhibitors.
β-NAD, a pyridine nucleotide and biologically active form of nicotinic acid, is a coenzyme necessary for the catalytic reaction of certain enzymes. It occurs in living cells primarily in the oxidized state. Serves as a coenzyme of the dehydrogenases, especially in the dehydrogenation of primary and secondary alcohols. NAD usually acts as a hydrogen acceptor, forming NADH which then serves as a hydrogen donor in the respiratory chain.
Many metabolites and enzymes of biological interest are present in tissues at low concentrations. With the use of β-NAD as a catalyst intermediate and several enzymes in a multistep system, known as enzyme cycling, much greater sensitivity for detection of these components is achieved. The reduced form, β-NADH, is fluorescent whereas β-NAD is not. This difference in fluorescence provides a sensitive fluorescent measurement of the oxidized or reduced pyridine nucleotides at concentrations down to 10-7 M.
Electron acceptor. β-NAD is a carrier for hydride ion, forming b-NADH. Hydride ion is enzymatically removed from a substrate molecule by the action of dehydrogenases such as malic dehydrogenase and lactic dehydrogenase. Such enzymes catalyze the reversible transfer of a hydride ion from malate or lactate to b-NAD to form the reduced product, b-NADH. Unlike b-NAD which has no absorbance at 340 nm, b-NADH absorbs at 340 nm (EmM = 6.22). The increase in absorbance at 340 nm with the formation of b-NADH is the basis for measurement of activity of many enzymes.

Dodavatel: MP Biomedicals
Popis: This product is fluorescein-5-isothiocyanate (FITC "Isomer I")-conjugated goat affinity purified F(ab')2 fragments to mouse immunoglobulins (IgG,IgA,IgM) and buffer salts.The total protein is measured by absorbance (A)280 nm); F/P ratio is calculated using absorbance at 491.5nm. Antibody titer of the affinity purified F(ab')2fragments is standardized with an in-house control by immunoelectrophoresis. The affinity purified F(ab')2 fragment is tested for purity at 10 mg/mL using immunoelectrophoresis. The product is goat F(ab')2; no trace of albumin, whole molecule IgG or Fc is detected. This product contains sodium azide. To prevent formation of toxic vapors, do not mix with strongly acidic solutions. To prevent formation of potentially explosive metallic azides in metal plumbing, always wash into drain with copious quantities of water.
