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: Restek

Highly base-deactivated spherical silica manufactured by Restek. Monomeric C8 bonding. Similar to Pinnacle® DB C18, but the shorter alkyl chain provides less hydrophobic retention. Less retention can be useful for shortening analysis time, if resolution is adequate. Replaces Hypersil® BDS C8 and Pinnacle® C8 Amine.

Supplier: Bioss

The innate immune system detects viral infection by recognizing various viral components and triggers antiviral responses. Like the toll-like receptor 3 (TLR3), the cytoplasmic helicase retinoic acid inducible gene protein 1 (RIG1/DDX58) recognizes double-stranded (ds) RNA, a molecular pattern associated with viral infection. Unlike TLR3 however, RIG1/DDX58 activates the kinases TBK1 and IKKe through the adaptor protein IPS1. These kinases then phosphorylate the transcription factors IRF3 and IRF7 which are essential for the expression of type-I interferons. RIG1/DDX58 is required for the production of interferons in response to RNA viruses including paramyxoviruses, influenza virus, and Japanese encephalitis virus.

These 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 cover 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.

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.

WNT1-inducible-signaling pathway protein 2 (WISP-2) is a member of the CYR61/CTGF/NOV (CCN) family of regulatory factors. WISP-2 is expressed in ectodermal, mesodermal, and endodermal lineages, including primary osteoblasts, fibroblasts, mesenchymal stem cells, and adipogenic precursor cells. WISP-2 is a canonical WNT ligand that regulates cell proliferation, adhesion, and metastasis. Secreted WISP-2 promotes mesenchymal precursor cell proliferation and maintains them in an undifferentiated state. In bone-forming osteoblasts, WISP-2 promotes osteoblast adhesion and inhibits osteocalcin production.
