Catalog Number: (BSENR-1654-100)
Supplier: Biosensis
Description: mCherry is an engineered derivative of one of a family of proteins originally isolated from Cnidarians (jelly fish, sea anemones and corals). The mCherry protein was derived from DsRed, a red fluorescent protein from so-called disc corals of the genus Discosoma. DsRed is a 223 amino acid ~28kDa protein similar in size and properties to GFP, but, obviously, produces a red rather than a green fluorochrome. The original DsRed was engineered extensively in the Tsien lab to prevent it from forming tetramers and dimers and to modify and improve the spectral properties (1-3). The resulting monomeric protein is useful for applications such as Förster Resonance Energy Transfer (FRET, also known as Fluorescence Resonance Energy Transfer). Several further cycles of mutation, directed modification and evolutionary selection produced mCherry, which is monomeric and has an excitation maximum at 587 nm and and emission maximum at 610 nm (4).

Description: Agar is a polysaccharide complex extracted by bleaching and hot water treatment of agarocytes from the red alga Rhodophyceae, and usually consisting of the genera Gelidium, Acanthopeltis, Ceramium, Pterocladia and Gracilaria. The algae are typically found in the Pacific and Indian Oceans and in the Sea of Japan. It is primarily composed of two different units: Agarose and Agaropectin; Agarose is a neutral gelling component which is composed of a linear polymer of alternating D-galactose and 3,6-anhydrogalactose units. Agaropectin is a non-gelling component which consists of D-1,3-glycosidically linked D-galactose units, some of which are sulfated at the 6th position.
Agar is specially purified for use in preparing solid culture media for microbiological and bacteriological applications.

Supplier: Industrial Physics
Description: SSPC-VIS 3 pictorial surface standard contains a series of 43 full-colour reference photographs to be used as a supplement to the SSPC standards for hand and power tool cleaned steel. Shows a total of seven different steel surfaces (four uncoated and three previously coated) before and after hand tool cleaning (SP 2), power tool cleaning with power wire brushes and sanding discs (SP 3), power tool cleaning to bare metal (SP 11), and commercial grade power tool cleaning (SP 15). It also contains pictures of SP 11 surfaces with a restored profile, a revised guide to the use of reference photographs, a new table of standards and conditions depicted and additional explanatory notes.

Supplier: Merck
Description: TLC plates, unmodified silica gel 60
This range of plates uses Merck silica gel 60 with a unique polymeric binder that results in a uniform, hard surface that will not easily crack or blister. The smooth, extremely dense plate coating ensures narrow bands and maximum separation efficiency with the lowest background noise. Layer thickness 200 μm and, particle size of 10 to 12 µm. Flexible aluminium plates that can easily be cut to match individual separation requirements. Two inorganic fluorescent indicators for UV detection of colourless substances. Samples which absorb shortwave UV at 254 nm are detected due to fluorescence quenching.

Description: mCherry antibody is ideal for western blotting. Fluorescent proteins such as Discosoma Red Fluorescent Protein (and its varients), and GFP are widely used in research practice. Both commonly serve as a markers for gene expression and protein localization. DsRed was isolated from sea anemone Discosoma sp. mushroom and GFP is originated from Aequorea victoria jellyfish. As DsRed and GFP share only 19% identity, therefore, in general, anti-GFP antibodies do not recognize DsRed protein and vice versa. Structurally, Discosoma red fluorescent protein is similar to Aequorea green fluorescent protein in terms of its overall fold (a β-can) and chromophore-formation chemistry. However, Discosoma red fluorescent protein undergoes an additional steps in the chromophore maturation and obligates tetrameric structure. All mCherry antibodies have been pre-absorbed to eliminate any potential cross-reactivity to human, mouse and rat serum proteins. The antibodies are also confirmed for non-reactivity to GFP protein.

Supplier: Merck
Description: Merck offers a broad variety of withdrawal systems that are tailor-made for barrels and drums. They are designed to ensure safe, easy and efficient solvent withdrawal-even of residual quantities-while meeting all relevant safety regulations.
The integrated solvent supply systems directly connect the solvent to the instrument or product line where it is needed. We provide systems for manual pressure build-up as well as inert gas pressurising, supplemented by a comprehensive selection of reducers, adapters and couplings that allow easy interconnection of all components. This way the user can precisely manage his solvent flow and thus optimizes the processes-and at the same time minimizes risks for the employees and the environment.

Supplier: Merck
Description: The PhotoCheck test set is designed for testing the wavelength accuracy of all Merck photometers and spectrophotometers. It can be used as a secondary standard for testing instruments according to DIN/ISO 9000 and ISO 14000. The stable colour solutions can be used to test the following spectrophotometer filters and wavelength settings: 445 and 446 nm, 520 and 525 and 690 nm. The accuracy of the wavelength setting and the linearity of the extinction measurement is checked with four solutions per wavelength. The traceability of these test solutions to international standards is guaranteed by examining them in a reference photometer that is checked against the primary standard (NIST standard). These values are properly documented and supplied as part of the set.

Description: Chromogenic media offer a method for rapid identification of characteristic bacterial enzymes. Merck offers a wide range of solid and liquid culture media that also permits the fluorescence detection of <i>E. coli</i> under the trade name Fluorocult®. Fluorocult® culture media have the same components as the standard media and additionally the substrate MUG. Some of the media also contain tryptophan as the substrate for a possible indole reaction to further confirm <i>E. coli</i> presence. The Fluorocult® method can produce a positive result within just 24 to 48 hours. In the case of the chromogenic media, a direct identification, using the characteristic colony colouring on the culture medium itself is possible without the application of further additives. A differentiation of positive single colonies is possible, even when high microbial counts are present.
