Supplier: Ahlstrom-Munksjö

Ahlstrom-Munksjö’s qualitative grades of filter paper are recommended for use in analytical methods which determine or identify particulate constituents of a mixture irrespective of the amount present. Qualitative filter papers are often used in routine separation work that still requires high purity and consistent performance. These filter papers covers a wide range of laboratory applications, as liquids clarification, qualitative analytical separations for precipitates and buffers filtration, and are also used for soil analysis and in food and beverage testing. Wet-strengthened grades contain a reinforcement agent that increases their resistance to rupture when wet, such as in vacuum filtration, and their resistance when filtering acidic solutions. High Purity hardened filter papers grades 1288 to 1291 are also produced from cellulose with an alpha content of nearly 100% resulting in an ash content of <0,1%.

CYP2A13 is 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 protein localizes to the endoplasmic reticulum. Although its endogenous substrate has not been determined, it is known to metabolize 4- (methylnitrosamino)-1- (3-pyridyl)-1-butanone, a major nitrosamine specific to tobacco.This gene encodes a member of the cytochrome P450 superfamily of enzymes.

Supplier: MEMMERT

This steriliser complies with all relevant standards and regulations for medical products and guarantees reliable programme sequences, irrespective of the load and chamber volume. Especially due to the SetpointWAIT function the validation of this hot air steriliser is possible anytime. The SetpointWAIT function ensures that the programme is only continued when the setpoint temperature has been reached. Precisely maintaining the sterilisation time and completely killing off even highly resistant microorganisms is therefore guaranteed at all times, irrespective of the sterilisation load and chamber volume. This feature can also be used with additional, freely positionable PT100 temperature sensors. In this case, sterilisation only begins when the setpoint temperature has been reached at all measurement points – that is, in the load. For the special application of depyrogenisation, the hot-air steriliser is ideal.

KRT13 is a member of the keratin gene family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. Most of the type I cytokeratins consist of acidic proteins which are arranged in pairs of heterotypic keratin chains. This type I cytokeratin is paired with keratin 4 and expressed in the suprabasal layers of non-cornified stratified epithelia.The protein encoded by this gene is a member of the keratin gene family.

This type I cytokeratin is paired with keratin 4 and expressed in the suprabasal layers of non-cornified stratified epithelia. Mutations in this gene and keratin 4 have been associated with the autosomal dominant disorder White Sponge Nevus. The type I cytokeratins are clustered in a region of chromosome 17q21.2. Alternative splicing of this gene results in multiple transcript variants; however, not all variants have been described.

WDR13 is a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD), which may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. WDR13 gene is widely expressed in various tissues, and located in chromosome X. The function of this gene has not been determined.This gene encodes a member of the WD repeat protein family.
