Popis: Self-contained ductless enclosures allow safe handling of organic, formaldehyde, acid gas, sulphur compounds, or ammonia chemical fumes and vapours, as well as particulates. Air inside the enclosures passes through carbon filters, and in some cases additional HEPA particulate filters, before being safely exhausted back into the laboratory. No outside ducting is required.

Popis: Anaerobic Agar (Brewer) is recommended for the isolation and sensitivity testing of anaerobic and microaerophilic organisms and study of colonial morphology. The medium contains sodium thioglycollate and sodium formaldehyde sulphoxylate which provides adequate anaerobiosis. Resazurin imparts pink colour to the media in presence of oxygen. Clostridium species grows luxuriantlly on the media.

Popis: Aldehyde dehydrogenase from baker′s yeast catalyses the reduction of pyridine nucleotides by several aldehydes. It catalyses the oxidation of a wide range of substrates, such as acetaldehyde, formaldehyde, propionaldehyde, n-butylaldehyde, isobutylaldehyde, n-valeraldehyde, caproaldehyde, benzaldehyde, glycoaldehyde, D-glyceraldehyde, malonic semialdehyde, and succinic aldehyde. The enzyme has been used to study the production of ethanol and isobutanol.

Popis: Nerve terminal probes are a series of fluorescent cationic styryl dyes developed to follow synaptic activity. These dyes have a lipophilic tail at one end and a hydrophilic cationically charged head group at the other end. The dyes vary in the number of carbons in the lipophilic tail (m) and the number of double bonds linking the two aromatic rings in the dye (n). AM dyes are similar to FM dyes, but contain an additional formaldehyde-fixable amino group in the cationic head.

Popis: Histone demethylase that specifically demethylates 'Lys-9' and 'Lys-36' residues of histone H3, thereby playing a central role in histone code. Does not demethylate histone H3 'Lys-4', H3 'Lys-27' nor H4 'Lys-20'. Demethylates trimethylated H3 'Lys-9' and H3 'Lys-36' residue, while it has no activity on mono- and dimethylated residues. Demethylation of Lys residue generates formaldehyde and succinate. Participates in transcriptional repression of ASCL2 and E2F-responsive promoters via the recruitment of histone deacetylases and NCOR1, respectively.

Popis: Melamine is combined with formaldehyde to produce melamine resin, a very durable thermosetting plastic used in Formica, and melamine foam, a polymeric cleaning product. The end products include countertops, dry erase boards, fabrics, glues, housewares and flame retardants. Melamine is one of the major components in Pigment Yellow 150, a colorant in inks and plastics.Melamine also enters the fabrication of melamine poly-sulfonate used as superplasticiser for making high-resistance concrete. Sulfonated melamine formaldehyde (SMF) is a polymer used as cement admixture to reduce the water content in concrete while increasing the fluidity and the workability of the mix during its handling and pouring. It results in concrete with a lower porosity and a higher mechanical strength exhibiting an improved resistance to aggressive environments and a longer life-time. The use of melamine as fertiliser for crops had been envisaged during the '50s and '60s because of its high nitrogen content (2/3).[7] However melamine is much more expensive to produce than other common nitrogen fertilisers, such as urea. To be effective as a fertiliser, it is essential that the plant nutrients are released or made available in a manner that matches the needs of the growing crop. The nitrogen mineralisation process for melamine is extremely slow, making this product both economically and scientifically impractical for use as a fertiliser.

Popis: PIPES is a zwitterionic N-substituted aminosulfonic acid "Good" buffer.
PIPES is used to buffer glutaraldehyde fixative solutions when fixing plant and/or animal tissue samples. This will help prevent the loss of lipids. It is also used to buffer glutaraldehyde and formaldehyde when fixing fungal zoospores for fluorescence microscopy and electron microscopy. PIPES tends to give optimal results.
Buffers can be made by adding a solution of base to PIPES free acid, titrating to the appropriate pH.

Popis: Cell proliferation dyes diffuse passively into cells and covalently label intracellular proteins, resulting in long term cell labelling. They are non-fluorescent until they are hydrolysed by intracellular esterase's. The dyes then react with intracellular amines forming fluorescent conjugates that are retained in the cell. Immediately after staining, a single, bright fluorescent population will be detected by flow cytometry. With each cell division, daughter cells inherit roughly half of the fluorescent label, allowing the number of cell divisions that occur after labelling to be detected by the appearance of successively dimmer fluorescent peaks on a flow cytometry histogram compared to cells analysed immediately after staining. Staining is formaldehyde fixable.

Popis: The protein named TrkB (also named Neurotrophic tyrosine kinase receptor type 2 (NTRK2), GP145-TrkB or Tropomyosin-related kinase B is a receptor tyrosine kinase involved in the development and the maturation of the central and the peripheral nervous systems and is important in the regulation of neuron survival, proliferation, migration, differentiation, and synapse formation and plasticity. TrkB may also play a role in neutrophin-dependent calcium signaling in glial cells and mediate communication between neurons and glia. TrkB is the primary receptor for BDNF (brain-derived neurotrophic factor. TrkB also binds NT4 and NT3 but less efficiently. (Reference: www.uniprot.org).

Applications: Flow Cytometry (5-10 ug/mL): Tested on human and rodent cell lines. Cell staining can be performed under native conditions on ice, or on fixed cells with up to 4% formaldehyde. Other applications have not been tested. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Popis: JMJD2B is a 1,064 amino acid protein encoded by the human gene JMJD2B. JMJD2B belongs to the JMJD2B histone demethylase family and contains one JmjC domain, one JmjN domain, two PHD-type zinc fingers and two Tudor domains. The two Tudor domains recognize and bind methylated histones and have an interdigitated structure; the unusual fold is required for its ability to bind methylated histone tails. JMJD2B is a histone demethylase that specifically demethylates Lys 9 residues of Histone H3, thereby playing a role in histone code. It does not demethylate Histone H3 Lys 4, H3 Lys 27, H3 Lys 36 or H4 Lys 20, however, and is only able to demethylate trimethylated H3 Lys-9 and has weaker activity than JMJD2A, JMJD2C and JMJD2D. JMJD2B demethyl-ation of Lysine residues will generate formaldehyde and succinate. JMJD2B is a ubiquitously expressed nuclear protein.
