mPrep/s™ WorkStation for TEM and SEM, Electron Microscopy Sciences

Supplier: ELECTRON MICROSCOPY SCIENCE

Everything you need to work efficiently while preparing your samples using mPrep/s™ capsules is easily accomplished with the mPrep/s™ WorkStation. Simply load the capsule onto the built-in insertion tool at the center of the workstation, detach the screen from the capsule, use the lever to open the screen and insert the specimen. Then release the lever and re-attach the capsule. Once loaded, the sample requires no additional handling - even for TEM embedding or SEM mounting.

Tricine ≥99%, white powder for electrophoresis

Supplier: MP Biomedicals

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.

Dextran, M.W. 60,000-90,000 clinical grade

Supplier: MP Biomedicals

Use of dextrans as long and hydrophilic spacer arms improves the performance of immobilized proteins acting on macromolecules. Dextrans are used in many applications as platelet aggregants, plasma volume extenders, osmotic pressure regulators, stabilizers, organ separation media, matrix components, copolymers, microcarriers, binding agents, viscosity modifiers, antithrombotics, lubricants and physical structure components. They may be used as long hydrophilic spacer arms to improve the performance (freedom of movement) of conjugated/bound proteins. Dextrans may be derivatized for use in biosensor systems.
Dextran is branched polysaccharide made up of linear α (1→6) linked glucose units and α (1→3) link initiated branches; it ranges in size from 10,000 to 150,000 Kd.Depending upon its molecular weight it has different uses in different fields.
Physical Appearance: White powder
Solubility: Very soluble in water (50 mg/mL), slightly soluble in alcohol
