Betaine, anhydrous, white powder for biochemistry

Supplier: MP Biomedicals
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.

β-D-Glucose ≥97%

Supplier: MP Biomedicals
Description: D-Glucose, a naturally occurring monosaccharide found in plants, is the primary energy source for living organisms. It is utilized as a metabolic intermediate by cells for either aerobic or anaerobic respiration. D-Glucose exists in two cyclic forms, α-D-glucose and β-D-glucose, based on the position of the substituent at the anomeric center. α-D-Glucose is the monomer unit in starch, whereas β-D-glucose is the monomer unit in cellulose.2 When one of these anomers is added to solution, it undergoes reversible epimerization to the other via an open-chain form, during which the specific rotation of the solution changes gradually until it reaches equilibrium. The existence of multiple binding modes of this single monosaccharide has been studied as a model scaffold to design compounds with increased probability of ligand binding.

Fluorescein-5-thiosemicarbazide

Catalog Number: (103011-026)
Supplier: Anaspec Inc
Description: 5-FTSC reacts with ketones to yield relatively stable hydrazones and with aldehydes to yield hydrazones that are somewhat less stable, though they may be formed faster (compared to ketones). These hydrazones are generally reduced with sodium borohydride (NaBH4) to further increase the stability of the linkage. 5-FTSC has been used to make a wide variety of biomolecules such as L-aspartase-a-decarboxylase, enzyme-oxidized live plant protoplasts, immunoglobulins, thrombin and antithrombin.

DAF-2 ≥95% (by HPLC)

Supplier: Adipogen
Description: DAF-2 is highly sensitive reagent for NO detection and determination of nitric oxide synthase activity. DAF-2, however, remains essentially nonfluorescent until it reacts with the nitrosonium cation (produced by spontaneous oxidation of nitric oxide) to form a fluorescent heterocycle, which becomes trapped in the cell's cytoplasm. This sensitive fluorescent probe has been used to identify individual nitric oxide-producing neurons in brain slices, in mitochondria and in living plant cells. Spectral data: lambdaex 505nm; lambdaem 518nm in 0.1M Tris pH8.0.

Human Recombinant Ferritin heavy chain (from E. coli)

Catalog Number: (75791-128)
Supplier: Prosci
Description: Ferritin heavy polypeptide 1(FTH1), is a ubiquitous intracellular protein which stores iron in a soluble, non-toxic, readily available form. FTH1 has ferroxidase activity and is important for iron homeostasis. Iron is taken up in the ferrous form and deposited as ferric hydroxides after oxidation. Ferritin is composed of 24 subunits of the light and heavy ferritin chains. It plays a role in delivery of iron to cells and mediates iron uptake in capsule cells of the developing kidney. Variation of ferritin subunit composition may affect iron absorption and release in different tissues. Deficiency of ferritin proteins may cause several neurodegenerative diseases. Almost all living organisms can produce this protein, including algae, bacteria, higher plants, and animals.

Cycloheximide (microbial) ≥94%, white powder

Supplier: MP Biomedicals
Description: 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.
