Popis: Tris have been useful as buffers in a wide variety of biological systems. It has been used as a starting material for polymers, oxazolones (with carboxylic acids) and oxazolidines (with aldehydes). It does not precipitate calcium salts and is of value in maintaining solubility of manganese salts. It can be used for the direct standardization of a strong acid solution; the equivalence point can be determined either potentiometrically or by use of a suitable indicator such as 3-(4-Dimethylamino-1-naphthylazo)-4-methoxybenzenesulfonic acid. It is RNAse and DNAse-free. Tris is relatively non-hygroscopic ; but, if needed, it can be dried at 100 °C for up to 4 hours to remove any water.
Tris is used in pH control in vitro and in vivo for body fluids and in buffering systems for electrophoresis applications.Tris is used in assays used to characterize the activity and kinetics of the enzymes that catalyze SUMOylation of Small ubiquitin-like proteins (SUMO) and SUMO-dependent protein-protein interactions.

Popis: PIPES is a zwitterionic N-substituted aminosulfonic acid "Good" buffer.
PIPES is used to buffer glutaraldehyde fixative solutions when fixing plant and/or animal tissue samples. This will help prevent the loss of lipids. It is also used to buffer glutaraldehyde and formaldehyde when fixing fungal zoospores for fluorescence microscopy and electron microscopy. PIPES tends to give optimal results.
Buffers can be made by adding a solution of base to PIPES free acid, titrating to the appropriate pH.

Popis: MP EcoChrom™ SILICA is used as a suspending and thickening agent in pharmaceutical.A silica-based aerogel was used in the Stardust spacecraft to collect extraterrestrial particles. Silica is also used in the extraction of DNA and RNA due to its ability to bind to the nucleic acids under the presence of chaotropes. As hydrophobic silica it is used as a defoamer component. In hydrated form, it is used in toothpaste as a hard abrasive to remove tooth plaque. SiO2 has a number of distinct crystalline forms (polymorphs) in addition to amorphous forms. In the majority of silicates, the Si atom shows tetrahedral coordination, with 4 oxygen atoms surrounding a central Si atom.

MP EcoChrom™ Silica, the chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with the chemical formula SiO2 with a mean pore size of 60Å and particles size of 200-500μm. MP silica are free of particles outside the standard range. The irregular shape of MP Silica permits the easy packing of column permeability and plate number. They allow easy switching from one sieve cut to another, offering an easy way to change the chromatographic methods. It has been known for its hardness since ancient times. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms.

Popis: The efficient removal of unincorporated dNTPs, salts and enzymes after any PCR is detrimental to the success or failure of downstream applications, such as genotyping, Sanger, and Next Generation Sequencing. The AxyPrep™ Mag PCR Clean Up Kit utilises a paramagnetic bead technology for rapid high throughput purification of PCR products. Additionally, the AxyPrep™ Mag PCR Clean Up Kit employs an optimised buffer to selectively bind PCR amplicons 60 bp and larger to paramagnetic beads, providing end users flexibility and high recovery options. The protocol comprises binding, washing and eluting steps, where primers, nucleotides, salts and enzymes in the reaction mixture are efficiently removed leaving a purified PCR product that is essentially free of contaminants. No centrifugation or filtration steps are required, allowing the process to be adapted to multiple commercially available automation platforms.
