Digestion of protein samples with sulphuric acid and catalyst requires prolonged periods of heating and is traditionally carried out in block heaters. The SpeedDigester design features IR heating that provides fast preheating and cool down. The models described below provide a range of flexible options with different levels of sophistication and control.

Supplier: CHIRAL TECHNOLOGIES

These protein-based columns are suitable for separation of acidic and non-protolytic compounds. These columns function entirely in the reversed phase chromatographic mode, using buffers with low organic modifier content and at moderate pH values.

Avantor® Partisil® was one of the first commercially available irregular silicas with a large surface area giving it a high loading capacity.

Supplier: ProSci Inc.

This gene encodes a transcription factor that was originally identified as a widely expressed mammalian DNA binding protein that could bind a tax-responsive enhancer element in the LTR of HTLV-1. The encoded protein was also isolated and characterized as the cAMP-response element binding protein 2 (CREB-2). The protein encoded by this gene belongs to a family of DNA-binding proteins that includes the AP-1 family of transcription factors, cAMP-response element binding proteins (CREBs) and CREB-like proteins. These transcription factors share a leucine zipper region that is involved in protein-protein interactions, located C-terminal to a stretch of basic amino acids that functions as a DNA binding domain. Two alternative transcripts encoding the same protein have been described. Two pseudogenes are located on the X chromsome at q28 in a region containing a large inverted duplication.

The E.Z.N.A.® Plasmid Maxi Kit is the maxi scale system to deliver high-quality plasmid DNA using the spin column format, without costly accessories. The HiBind® DNA Maxi column facilitates the binding, washing, and elution steps, thus enabling multiple samples to be simultaneously processed. Although yields vary according to plasmid copy number, E.coli strain, and conditions of growth, 50 to 200 ml of overnight culture in LB medium typically produces 0,5 to 1 mg of high copy number plasmid DNA. Up to 500 ml of culture may be processed when working with low copy number plasmid. The product is suitable for automated fluorescent DNA sequencing (typical reads exceed 800 bp), restriction enzyme digestion, transfection of mammalian cells, transcription invitro, and other applications.

Cogent Amide™ has an amide functional group bonded to the silica-hydride surface direct silicon-carbon bonds. Since the ligand is attached to the surface with direct silicon carbon bonds the bonded phase does not hydrolyze in acidic conditions. Also, it does not make a strong association with acetone.

Where an AnaeroGen sachet is placed in a sealed jar, the atmospheric oxygen in the jar is rapidly absorbed with the simultaneous generation of carbon dioxide. This novel method differs from others commonly used in that the reaction proceeds with no evolution of hydrogen, and therefore, does not require a catalyst. Furthermore, water is not required to activate the reaction. When used as directed, the AnaeroGen sachet will reduce the oxygen level in the jar to below 1% within 30 minutes. The resulting carbon dioxide level will be between 9% and 13%.
CampyGen Compact for 1 or 2 Petri dishes, is a simple system for generating microaerobic conditions. The system consists of a plastic pouch and sealing clip and a paper gas generating sachet. The paper sachet contains ascorbic acid which reacts on contact with air to produce the microaerobic conditions for the growth of microaerophilic organisms.
