Supplier: Bioss

The Cyp46 gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This endoplasmic reticulum protein is expressed exclusively in the brain, where it converts cholesterol to 24S-hydroxycholesterol by adding a hydroxyl group to cholesterol, producing a product that is more soluble than cholesterol and able to be exported from the brain.Cyp46 is also known as 24S-cholesterol hydroxylase.

Supplier: WTW

A wide choice of tests is available, for routine quantitative analysis in different applications, designed for use with WTW spectrophotometers and photometers. The test is automatically recognised by the laboratory instruments (via a barcoding system) and results are displayed in the appropriate units. Due to the different photometer optics, one test may yield different measuring ranges in different instruments; LED photometers may have smaller measuring ranges for the same test.

Supplier: MICROSOLV

Supplier: VWR Collection

Weights made from anti-magnetic, polished stainless steel. Suitable for medium resolution precision electronic balances. Weights have adjustment cavities for weights of more than 20 g.

Supplier: MERKLINGER PRAZISION WERKZEUG

This column-packing technology is based on a combination of vacuum suction with subsequent column bed compression that stabilises the packing. A common water-jet pump is used to generate the vacuum. The sorbent slurry is sucked through a packing reservoir into the column by applying low pressure at the bottom end of the column.

Supplier: Restek

Ultra C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape. It is made of high-purity, type-B silica that minimises activity and creates high-density bonding. These columns are designed for selective and reliable HPLC applications.

Supplier: ERGOMAT

The Ergomat Softline is made from nitrile rubber and is designed to increase comfort while reducing tripping hazards, body aches, quality issues, and sick leaves.
