Description:
The two major cytoskeletal proteins implicated in cell motility are actin and myosin. Actin and myosin are constituents of many cell types and are involved in a myriad of cellular processes including locomotion, secretion, cytoplasmic streaming, phagocytosis and cytokinesis. Although actin is one of the most conserved eukaryotic proteins, it is expressed in mammals and birds as at least six isoforms characterized by electrophoresis and amino acid sequence analysis. Four of them represent the differentiation markers of muscle tissues and two are found in practically all cells.

Description:
Betaine is a quaternary amine found in bacteria and higher plants which acts as an osmoprotectant (able to restore and maintain osmotic balance in living cells) and enhances the freezing tolerance of of living organisms. This is probably due to its involvement in the protection of macrocomponents of plant cells, such as protein complexes and membranes, under stress conditions. Betaine is biosynthesized in living cells by a two-step oxidation method from choline. The primary enzyme involved in this biosynthesis is choline oxidase.

Description:
Alpha Actinin is an actin binding protein present in both muscle and non-muscle cells. It has a molecular weight of 100,000 daltons and forms dimers in solution. In normal skeletal muscle alpha actinin is associated with the z-discs that define muscle sarcomeres. In smooth muscle alpha actinin has been detected in dense bodies and plaques characteristic of the tissue. Immunofluorescent labeling of a large variety of cells using antibody to alpha actinin reveals extensive association of the proteins with actin containing stress fibers and in particular with their membrane bound termini.

Description:
Phenol red is an acid-base indicator. It is made by condensing two moles of phenol with one mole of o-sulfobenzoic acid anhydride.
Phenol Red is used as a pH indicator in cell culture applications. A solution of phenol red will have a yellow color at a pH of 6.4 or below and a red color at a pH of 8.2 and above. Phenol red in tissue culture media can act as a weak estrogen, especially with human breast cancer cells. Phenol red can be used to measure hydrogen peroxide in cultured macrophages in multiwell plates. Store at Room Temperature (15-30 °C)

Description:
PMA (Phorbol-12-Myristate-13-Acetate) is a diester of phorbol and is a tumor promoting compound extracted from croton oil. It is a reversible, highly potent protein kinase C (PKC) activator in vitro and in vivo at nM concentrations. PMA’s effects on PKC are attributed to its similarity to diacylgylerol, a natural activator of PKC.
PMA activates Ca2+- ATPase and potentiates forskolin-induced cAMP formation. It has been shown to inhibit apoptosis induced by the Fas antigen, but PMA induces apoptosis in HL-60 promyelocytic leukemia cells. Potent tumor promoter; activates protein kinase C in vivo and in vitro. Store at -20 °C. Protect from light.

3- (4,5-Dimethyl-2-thiazolyl-2)-2,5-diphenyl-tetrazolium bromide is used as a colorimetric metabolic activity indicator in cell viability assays. Thiazolyl Blue Tetrazolium Blue (MTT) is a dye used in measurement of cell proliferation. MTT produces a yellowish solution that is converted to dark blue, water-insoluble MTT formazan by mitochondrial dehydrogenases of living cells. The blue crystals are solubilized with acidified isopropanol and the intensity is measured colorimetrically at 570 nm. MTT has been used as a histochemical/cytochemical reagent and for the detection of NAD. ADP-linked enzyme systems in tissue cannot be detected with MTT, due to binding of the cation by the cyanide trap used. MTT is rapidly reduced to the formazan, which chelates with nickel, copper, and cobalt; the cobalt chelate has been used in oxidative systems.

Applications
Cycloheximide is used in protein synthesis in apoptosis. It is also used in plant research to study disease resistance and as an ethylene stimulant, useful in studies involving fruit and leaf production. Product Description 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. It 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. Biochem/physiol Actions 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.

Dimethyl Sulfoxide is a dipola, aprotic solvent. It has been shown to accelerate strand renaturation (1-10% concentration) and is believed to give the nucleic acid thermal stability against depurination. Dimethyl Sulfoxide is used to enhance dermal absorption of many chemicals, as a solvent for many organic and inorganic compounds including fats, carbohydrates, dyes, resins, and polymers, in antifreeze or hydraulic fluids, as a cryopreservative for cell cultures, oxidation of thiols and disulfides to sulfonic acids, as a PCR cosolvent to help improve yields, especially in long PCR. DMSO is routinely used in polymerase chan reaction (PCR), amplification of cDNA libraries, DNA sequencing, column-loading buffers for poly (A)+ RNA selection, buffers for the transformation of competent E. coli, and transfection protocols. To prepare sterile solutions use a teflon or nylon membrane to sterile-filter the DMSO - do not use a cellulose acetate membrane.
