QUANTOFIX® test strips meet all requirements of a modern rapid test. The colour of the reactive pad changes depending on the concentration of an analyte in the sample. The evaluation is usually carried out visually by comparison of the reaction colour with a multi-stage colour scale. These test strips are immediately ready-to-use. They do not require additional accessories. The test strips are intended for single use, maintenance or calibration are not required.

Poly-lysine is a polycation which binds to DNA, red cell membrane and any negatively charged protein. When adsorbed to the culture surface, poly-lysine increases the number of positively charged sites available for cell binding. A compromise between the easier to use lower molecular weight products and the extremely viscous higher molecular weights would be the products in the range of 70,000-150,000.
It is typically used as a coating substrate for culture dishes, slides, etc. It enhances electrostatic interaction between negatively charged ions of the cell membrane and the culture surface. Both the D- and L- form of the poly-lysine can be used as a coating substrate since poly-lysine is a nonspecific attachment factor for cells; however, certain cells can digest poly-lysine. In this case, poly-D-lysine should be used as the attachment factor so that the cells are not disrupted by excessive uptake of L-lysine.
Other uses for poly-lysine have been reported as well:
• Conjugation to methotrexate for increased drug transport.
• Microencapsulation of islets.
• Use in simple reproducible procedure for chromosomal preparations from a variety of tissues.
• Immobilation of living cells in biocompatible semipermeable microcapsules.
• In the preparation of polycationic beads.
• Conjugation to albumin and horseradish peroxidase to enhance cellular uptake.
Poly-D-lysine hydrobromide is a synthetic amino acid that enhances cell adhesion to solid substrates. It has additionally been shown to eliminate prion proteins from infected cells.

The Optima™ range of advanced thermostats can be combined with plastic baths, premium stainless steel baths or refrigeration units. The TX150 and TXF200 thermostats feature a full colour QVGA TFT screen displaying actual and set temperature and clear status icons. The QVGA TFT screen, in combination with the easy to use dial and function keys, allows rapid navigation through the intuitive menu system. Both units have RS232 and USB interfaces and can be programmed via remote PC or laptop using Grant’s versatile Labwise™ software (optional). Additional features include countdown timer, adjustable over-temperature cut-out, visual, audible and programmable high and low temperature alarms. The TX150 has the capacity to store one program with 30 segments. The TXF200 can also be programmed via the user interface and can store up to 10 programs containing 100 segments. The programming interface includes set target temperature with a choice of time to target temperature or temperature ramp speed and an additional programmable relay for on/off control of ancillary equipment or refrigeration units.

Pyruvic acid is an intermediate in sugar metabolism and in enzymatic carbohydrate degradation (alcoholic fermentation) where it is converted to acetaldehyde and CO2 by carboxylase. In muscle, pyruvic acid (derived from glycogen) is reduced to lactic acid during exertion, which is reoxidized and partially retransformed to glycogen during rest. It improves coliform recovery when present in culture medium. It is involved in a metabolic regulatory pathway activated by mitochondrial oxidants. Pyruvate is involved in respiratory regulation in plants by interacting with alternative oxidase at a conserved cysteine residue. It may help prevent hydrogen peroxide mediated cell death.
Sodium pyruvate is utilized as a component in culture broth and media. Sodium pyruvate is used in Wallen fermentation medium to enhance the conversion of oleic acid to 10-ketostearic acid by Bacillus sphaericus. Sodium pyruvate has also been used to establish stably transfected human B cell lines.
Sodium Pyruvate has shown antioxidant properties and protective effects against oxygen radicals. Pyruvate is produced as part of glycolysis and is an intermediate in many metabolic pathways. It can be converted into acetyl CoA and enter the TCA Cycle.

FBXO25 is a member of the F-box protein family which is characterized by an approximately 40 amino acid motif, the F-box. The F-box proteins constitute one of the four subunits of ubiquitin protein ligase complex called SCFs (SKP1-cullin-F-box), which function in phosphorylation-dependent ubiquitination. The F-box proteins are divided into 3 classes: Fbws containing WD-40 domains, Fbls containing leucine-rich repeats, and Fbxs containing either different protein-protein interaction modules or no recognizable motifs. The protein belongs to the Fbxs class. Three alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.This gene encodes a member of the F-box protein family which is characterized by an approximately 40 amino acid motif, the F-box.
