Catalog Number: (76177-882)

Supplier: MP Biomedicals

Description: Storage: Room Temperature
Polysorbate 20 is nonionic surfactants derived from sorbitan ester, it is soluble or dispersible in water but differ widely in organic and oil solubility.
Polysorbate 20 is typically used as an emulsifying agent for the preparation of stable oil-in-water emulsions, particularly in pharmaceutical applications. It is also used in pre-extraction of membranes to remove peripheral proteins & as a blocking agent on nitrocellulose at a typical concentration of 0.05%.
Series of nonionic surfactants derived from sorbitan esters. They are soluble or dispersible in water but differ widely in organic and oil solubilities. Used as oil-in-water emulsifiers in pharmaceuticals, cosmetics, cleaning compounds, etc.

Sesame oil NF

Supplier: Spectrum Chemicals

Description: SESAME OIL, NF also known as til oil, is an oil derived from the sesame seed. As an edible vegetable oil, it is widely used in most Eastern and some Middle Eastern cuisine's as a flavor eNHancer. It is also used in the personal care industry in soap production, as cosmetic oil carrier and as the base for massage oils. Medicinally, its major use is as a solvent in the preparation of sustained-release intramuscular / subcutaneous injections of oil soluble actives such as steroids and avermectins. It is also used as an excipient in suspensions and emulsions, ointments, liniments, ophthalmic preparations, oral capsules and suppositories. Spectrum Chemical NF SESAME OIL products are manufactured, packaged and stored under current Good Manufacturing Practices (cGMP) per 21CFR part 211 in FDA registered and inspected facilities. Storage temperature - LIGHT SENSITIVE: Keep tightly closed in light-resistant containers. Prevent exposure to excessive heat.

Glutaraldehyde solution 50% in aqueous solution

Supplier: MP Biomedicals

Description: Glutaraldehyde is a bifunctional protein cross-linking reagent, reacting with NH2 groups to form Schiff's bases.
Sporicidal agent. Glutaraldehyde reacts through cross-linking to impart water resistance to protein and polyhydroxy compounds. It is also a reducing agent for photochemicals. In organic syntheses, the reactive carbonyl groups of glutaraldehyde suggest its use as an intermediate for the production of resins, dyestuffs, and pharmaceuticals. Glutaraldehyde is a disinfectant, which is rapidly effective against vegetative forms of Gram-positive and Gram-negative bacteria. It is also effective against acid-fast bacteria, bacterial spores, some fungi and viruses, including hepatitis B virus and human immunodeficiency virus. It can also be used for stabilization of proteins on agarose beads, activation of polystyrene and glass for immobilization of antibodies and antigens, and coupling peptides onto carrier proteins. Can be used for preparing emulsions for making photographic film. Also for use as an electron microscopy fixative or cell fixation.

Agar (from Red Alga Rhodophyceae), pale yellow powder USP

Supplier: MP Biomedicals

Description: Agar is a polysaccharide complex extracted by bleaching and hot water treatment of agarocytes from the red alga Rhodophyceae, and usually consisting of the genera Gelidium, Acanthopeltis, Ceramium, Pterocladia and Gracilaria. The algae are typically found in the Pacific and Indian Oceans and in the Sea of Japan. It is primarily composed of two different units: Agarose and Agaropectin; Agarose is a neutral gelling component which is composed of a linear polymer of alternating D-galactose and 3,6-anhydrogalactose units. Agaropectin is a non-gelling component which consists of D-1,3-glycosidically linked D-galactose units, some of which are sulfated at the 6th position.
Agar is typically used in (According to the Merck Index): Substitute for gelatin, isinglass, etc. in making emulsions including photographic, gels in cosmetics, and as thickening agent in foods especially confectionaries and dairy products; in meat canning; in production of medicinal encapsulations and ointments; as dental impression mold base; as corrosion inhibitor; sizing for silks and paper; in the dyeing and printing of fabrics and textiles; in adhesives. In nutrient media for bacterial cultures.

Cycloheximide, white powder cell culture reagent

Supplier: MP Biomedicals

Description: Cycloheximide is a glutarimide antibiotic derived from a microbial source. Cycloheximide is an antibiotic which is very active against many molds, yeasts, and phytopathogenic fungi. It exhibits somewhat lower activity against bacteria and certain fungi. Control of various molds and fungi in gelatin-based photographic emulsions, photoengraving glues, and other light-sensitive products is suggested.
Cycloheximide is used in plant research to study disease resistance and as an ethylene stimulant, useful in studies involving fruit and leaf production. It is also used in bacteriological media to isolate or count bacteria in the presence of yeast and molds; Used in protein synthesis in apoptosis; Gene expression; Glycogenolysis, gluconeogenesis and ureogenesis in isolated rat hepatocytes; Studies involving steroidogenesis; Used in plant regulation and as a quality control measure by the food and beverage industry.
Cycloheximide (CHX) is an antibiotic produced by S. griseus. Its main biological activity is translation inhibition in eukaryotes resulting in cell growth arrest and cell death. CHX is widely used for selection of CHX-resistant strains of yeast and fungi, controlled inhibition of protein synthesis for detection of short-lived proteins and super-induction of protein expression, and apoptosis induction or facilitation of apoptosis induction by death receptors. Cycloheximide inhibits peptide synthesis in eukaryotic organisms but not in prokaryotes. Protein synthesis is blocked by the interaction of cycloheximide with the translocase enzyme. This interaction prohibits the translocation of messenger RNA on the cytosolic, 80S ribosomes without inhibiting organelle protein synthesis. Cycloheximide is also known to induce FAS/FAS Ligand apoptosis, and triggers apoptosis in HL-60 cells, T-cell hybridomas, Burkitt's lymphoma cells in addition to a variety of other cell types. Cycloheximide will also delay or inhibit apoptosis induced by other agents.
