Cetyltrimethylammonium bromide is a phase transfer catalyst ideal for the precipitation of DNA. Hexadecyltrimethylammonium bromide is a bactericidal, cationic detergent. Its activity is neutralized by soaps and anionic detergents (i.e., SDS). Trimethylammonium bromide compounds form insoluble complexes with SDS. It is active at alkaline pH against both Gram positive and Gram negative organisms.

Cetyltrimethylammonium bromide ia used as an cationic surfactant suitable for the isolation of high molecular weight DNA in plants and other organisms(by a rapid method) as well as plant DNA for use in PCR analysis. It has been used to precipitate nucleic acids. CTAB provides enhancement of Concanavalin A mediated agglutination. It has been used for the determination of protein molecular weights in electrophoretic systems and for determination of critical micelle concentration of detergents. CTAB has also been used as a titrant for potentiometric titration of perchlorate and as a phase-transfer catalyst in reduction of arenes and heterocyclic compounds.

EHEC is capable of inducing life threatening illnesses, particularly in people with immune deficiency, young children and the elderly. Although the most common cause of EHEC is E. coli O157, other serotypes, such as O26, O45, O103, O111, O121 and O145, are also relatively frequent causes of infection. Typical symptoms are severe abdominal pain and diarrhoea, which is initially watery but often becomes bloody. E. coli are gram-negative, non sporulating, facultative anaerobic bacilli. Amongst the pathogenic E. coli, Verotoxin-forming strains (STEC or VTEC) have gained importance in recent years. The group of enterohaemorrhagic E. coli (EHEC) with its highly pathogenic serovar O157:H7 strain is particularly interesting in this respect. The main sources of infection are contaminated, raw or insufficiently heated foods of animal origin, such as meat and dairy products. The reservoir for EHEC is the gut of ruminants. Microorganisms can enter food during the processing of meat and dairy products if hygienic conditions are inadequate. The drastic increase in the incidence of food contamination caused by E. coli O157 demands reliable and rapid methods of detection. Innovative, rapid tests make screening for pathogenic organisms easier. Complete test sets for the detection of pathogens and toxins. The one-step format reduces the possibility of errors during handling. In addition to tests for the most common cause of infection, E. coli O157, there exits a 24-H screening protocol for VTEC, including E. coli O104:H4, based on Rapidcult™ E. coli enrichment combined with detection using Duopath® Verotoxins.

Interleukin-12 (IL-12), also known as Natural Killer Cell Stimulatory Factor (NKSF) or Cytotoxic Lymphocyte Maturation Factor (CLMF), is a heterodimeric pleiotropic cytokine made up of a 40 kDa (p40) subunit and a 35 kDa (p35) subunit. IL-12 is produced by macrophages and B lymphocytes and has been shown to have multiple effects on T cells and Natural Killer (NK) cells. Some of these IL-12 activities include the induction of IFN-gamma and TNF in resting and activated T and NK cells; the enhancement of cytotoxic activity of resting NK and T cells, the stimulation of resting T cell proliferation in the presence of a comitogen; and the enhancement of NK cell proliferation. Current evidence indicates that IL-12 is a key mediator of cellular immunity and induces the differentiation of Th1 cells from precursor T helper cells. Based on its activities, it has been suggested that IL-12 may have therapeutic potential as a vaccine adjuvant that promotes cellular immunity and as an antitumour and anti viral agent.

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.
