MES is a zwitterionic buffer. One of the "Good" buffers developed for biological applications. It has the advantages of maximum water solubility and minimum solubility in all other solvents, minimal salt effects, minimal change in pK with temperature, chemically and enzymatically stable, minimal absorption in visible or UV spectral range.
A buffer using MES free acid can be prepared by titrating the free acid with sodium hydroxide to the desired pH (pKa ± 1). Alternatively, volumes of equimolar MES free acid and sodium or potassium MES can be mixed to attain the desired pH.

Absorbs the widest range of acids, bases and unknown liquids - even those with high concentrations like 98% sulfuric acid and 30% sodium hydroxide. Chemical-resistant mat won't degrade or cause a dangerous reaction upon contact with corrosive spills. Eight layers of 100% polypropylene are thermally bonded to make PIG Mat exceptionally strong; won't rip, tear or fray even when saturated. Exclusive dimple pattern speeds wicking of liquid throughout mat for faster, easier cleanup. Highly absorbent, fine-fiber construction won't leave behind liquids or fiber residue.

Absorbs the widest range of acids, bases and unknown liquids, even those with high concentrations like 98% sulfuric acid and 30% sodium hydroxide. Chemical-resistant pillow won't degrade or cause a dangerous reaction upon contact with corrosive spills. Pillow has large surface area, high capacity and fast-wicking filler to quickly soak up liquids; great for adding absorbency during spill response. Polypropylene skin resists chemicals and tearing; reduces dust and holds in liquid, even when saturated. Polypropylene filler is highly absorbent for containing corrosive or reactive spills.

Make teaching diffusion easy. Exclusively from Ward's Science, we've pre-mixed, pre-poured, pre-measured and pre-cut these agar cubes to save you time and eliminate messy preparation in your lab. Just open the jar and begin using. Prepared to align with Ward's AP Biology Investigation 4: Diffusion and Osmosis, these cubes are also ideal for use on their own, or in any lab activity demonstrating the topic of diffusion. Agar cubes are prepared in three sizes (approximately 1cm, 2cm, and 3 cm). Phenolphthalein has been added to the cubes to exhibit a vivid fuchsia color during production and stored in a solution of sodium hydroxide. Just add an acid such as vinegar to demonstrate diffusion.

Thioglycolic acid protects tryptophan in amino acid analysis,and also mediates formation of ATP from ADP. It lowers the oxidation-reduction potential and neutralises mercurial preservatives. An inhibitor of fatty acid oxidation. An agent that prevents the metabolism of fatty acids and stimulates feeding. The sodium salt form is typically used in production of bacteriological culture media. The free acid is used as a reagent for the sensitive detection of iron (a blue color appears in the presence of ferric iron, and when an alkali hydroxide is added to a solution containing ferrous salts and thioglycolic acid, a yellow precipitate forms), molybdenum, silver and tin; used for the extraction and spectrophotometric determination of various transition metals such as lead, tungsten, molybdenum and titanium.

Tricine was first prepared by Good for use as a buffer for chloroplast reactions. It is structurally similar to Tris, but is much less inhibitory at high concentrations. For ATP assays using firefly luciferase, tricine buffer at 25 mM was found to be the best of ten common buffers tested.
Tricine is used as buffer component for separation of low molecular weight peptides. Tricine can be used in cryopreservation medium for the preservation of tissues and organs. Cryopreservation depends on the physical and chemical characteristics of the preservation medium used. The pH values and pK values for tricine/DMSO mixtures has been reported down to -20 °C. Tricine has been found to be an efficient scavenger of hydroxyl radicals in a study of radiation-induced membrane damage. Tricine is typically the buffer of choice in SDS-PAGE systems when separating proteins in the range of 1 to 100 kDa.
A buffer may be prepared by titrating with sodium hydroxide to the desired pH, using about a half-equivalent of NaOH.

A vitamin/enzyme cofactor found in milk, eggs, malted barley, liver, kidney, heart, leafy vegetables. Richest natural source is yeast. Occurs in the free form only in the retina of the eye, in whey, and in urine; bioactive forms occurring in tissues and cells are riboflavin monophosphate and flavine-adenine dinucleotide. Used as a photoinitiator for polymerization of polyacrylamide gels. It forms free radicals in aqueous solution in the presence of light. Riboflavin photodecomposes to leucoflavin. No free radicals are formed in the absence of oxygen but traces of oxygen allows for leucoflavin to reoxidize with free-radical generation. The catalysts TEMED or DMAPN are commonly added to speed up the free radical formation. The free radicals will cause acrylamide and bis-acrylamide to polymerize to form a gel matrix which can be used for electrophoresis. Riboflavin is commonly used in the stacking gel for non-denaturing polyacrylamide electrophoresis because native proteins can be senstive to persulfate ions from ammonium persulfate. Another advantage of riboflavin over ammonium persulfate is that it will not start polymerization until the gel is illuminated. Riboflavin causes less denaturing than other initiators. Gel strength can be improved when used with PTO (Pyrithione). Soluble in 0.1 M Sodium Hydroxide (50 mg/ml - clear, yellowish-orange solution); only slightly soluble in water.
