Product Keywords: Pharmaceutical Excipients; Excipients for Solid Dosage Form; Alitame; Sweeteners Excipients; Sweetening agent; 80863-62-3; 80863-62-3. UNII: NA. Chemical Name: L-α-Aspartyl-N-(2, 2, 4, 4-tetramethyl-3-thietanyl)-D-alanina-mide anhydrous; L-α-Aspartyl-N-(2, 2, 4, 4-tetramethyl-3-thietanyl)-D-alanina-mide hydrate. Grade: Pharmceutical Excipients. Stability and Storage Conditions: Alitame is stable at dry room temperature and degrades at high temperature or low pH. In the first stage, allose degrades to aspartic acid and alanine (under caustic conditions), and in the second stage it degrades slowly, first to β-aspartic acid isomers and then to aspartic acid and alanine. At pH 5 - 8, the half-life of alose solution at 23°C is about 4 years. At pH 2, the half-life of allose solution at 23°C is 1 year. Allocate should be kept in an airtight container in a cool and dry place. Source and Preparation: Alitame can be synthesized in a variety of ways. For example, dissolve 3- (d-alanamide) -2, 2, 4, 4-tetramethylthiocentine (thietane) in water, then add L-aspartic acid n-thiocarboxylic anhydride in sections, stir vigorously, maintain pH 8.5 - 9.5, then adjust pH to 5.5.

| Murexide | REAGENT (NH4C8H4N5O6, or C8H5N5O6·NH3), also called ammonium purpurate or MX, is the ammonium salt of purpuric acid. It may be prepared by heating alloxantin in ammonia gas to 100°C, or by boiling uramil (5-aminobarbituric acid) with mercury oxide. W.N. Hartley found considerable difficulty in obtaining specimens of REAGENT sufficiently pure to give concordant results when examined by means of their absorption spectra, and consequently devised a new method of preparation for REAGENT. In this process alloxantin is dissolved in a large excess of boiling absolute alcohol, and dry ammonia gas is passed into the solution for about three hours. The solution is then filtered from the precipitated REAGENT, which is washed with absolute alcohol and dried. The salt obtained in this way is in the anhydrous state. It may also be prepared by digesting alloxan with alcoholic ammonia at about 78°C; the purple solid so formed is easily soluble in water, and the solution produced is indistinguishable from one of REAGENT.REAGENT in its dry state has the appearance of a reddish purple powder, slightly soluble in water. In solution, its color ranges from yellow in strong acidic pH through reddish-purple in weakly acidic solutions to blue-purple in alkaline solutions. The pH for titration of calcium is 11.3.Justus von Liebig and Friedrich Wöhler in Giessen, Germany, had investigated the purple product, REAGENT, obtained from snake excrement in the 1 | |

| X-Gal (5-Bromo-4-chloro-3-indolyl-b-D-galactoside galactopyranoside, Xgal) | Blue substrate used in the detection of b-galactosidase in bacteria or phage as a selection agent for cloning experiments utilizing the lacZ vector. Colonies expressing b-galactosidase will appear blue in the presence of XGAL. Others will appear white.Gene Cloning:In gene cloning, X-gal is used as a visual indication of whether a cell expresses a functional β-galactosidase enzyme in a technique called blue/white screening. This method of screening is a convenient way of distinguishing a successful cloning product from other unsuccessful ones.The blue/white screening method relies on the principle of α-complementation of the β-galactosidase gene, where a fragment of the lacZ gene (lacZα) in the plasmid can complement another mutant lacZ gene (lacZΔM15) in the cell. Both genes by themselves produce non-functional peptides, however, when expressed together, as when a plasmid containing lacZα is transformed into a lacZΔM15 cells, they form a functional β-galactosidase. The presence of an active β-galactosidase may be detected when cells are grown in plates containing X-gal, the blue-colored product precipitated within cells resulted in the characteristic blue colonies. However, the multiple cloning site, where a gene of interest may be ligated into the plasmid vector, is located within the lacZα gene.... . Group: Biochemicals.

| Human Factor XIII | Factor XIII is the zymogenic form of the glutaminyl-peptide g-glutamyl transferase factor XIIIa (fibrinoligase, plasma transglutaminase, fibrin stabilizing factor, E.C. 2.3.2.13). Factor XIII is unique among transamidases in that it is a zymogen in vivo. Factor XIII is found both extracellularly in plasma and intracellularly in platelets, megakaryocytes, monocytes, placenta, uterus, liver and prostrate tissues. Plasma factor XIII is synthesized in the liver and circulates as a tetramer (Mr=320,000), composed of 2 pairs of nonidentical subunits (A2B2). The intra-cellular forms are synthesized in the tissues where they reside as dimers (Mr=146,000) of 2 identical A chains (A2). The A ...nly after the Ca2+ (Kd=10-3M) and fibrin(ogen) (Kd=10-8M) dependent dissociation of the B subunit dimer from the A2' dimer.In the coagulation cascade, factor XIIIa functions to stabilize the fibrin clot by crosslinking the a and g-chains of fibrin. Other proteins known to be substrates for Factor XIIIa which may be hemostatically important include fibronectin, α2-antiplasmin, collagen, factor V, von Willebrand Factor and thrombospondin.Factor XIII is purified from fresh frozen human plasma by a modification of the procedures described by Folke and Lorand involving barium citrate, ammonium sulfate and glycine precipitations, ion exchange chromatography and gel filtration.
