Planetary mills pulverise and mix soft, medium-hard to extremely hard, brittle and fibrous materials quickly without loss. Examples of applications include minerals, ores, chemicals, ceramics, soils, household and industrial waste and sample preparation for spectral analysis. These mills are suitable for long term trials and continuous use and are used for dry and wet grinding in all industry sectors, where a high degree of reproducibility, fineness, purity and speed is required. The excellent performance is achieved by the high centrifugal forces and very high pulverisation energy generated by the planetary mill design. The control system allows the operator to control speed, grinding time, direction reversal and interval times. The mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processes. Safety features include automatic safety self-test and a noise protected and ventilated chamber. A backup memory in the event of power failure ensures storage of remaining grinding time. Grinding sets are available in six different materials that allow sample preparation without contamination.

The majority of genomic DNA extraction methods involve numerous physical manipulations, including mixing, pipetting, shaking, binding to resin, elution, which results in sheared DNA that may not be suitable for further analysis.

E.Z.N.A.® Plasmid Midi Kit offers a novel and reliable method of isolating up to 200 µg of plasmid DNA in less than 60 minutes. This kit combines HiBind® membrane technology with the time-tested consistency of alkaline SDS lysis of bacterial cells to deliver high-quality plasmid DNA. The DNase/RNase-free HiBind® DNA midi columns operate by eliminating time consuming phenol-chloroform extractions and alcohol precipitations. Plasmid purification using the E.Z.N.A.® Plasmid Midi Kit follows a simple bind-wash-elute procedure thereby making it possible for multiple samples to be processed. Although yields vary according to plasmid copy number, E.coli strain, and conditions of growth, 50 ml of an overnight culture in LB medium will typically produce 200 µg of high-copy number plasmid DNA. When working with low-copy number plasmids the starting culture volume can be increased up to 100 ml. High-quality DNA is ready for immediate use in routine molecular biology applications, such as automated fluorescent sequencing, restriction enzyme digestion, and transfection screening.

Hamilton CO-RE tips were designed for MICROLAB pipetting workstations in order to solve the problem of sealing and alignment plagued by press-fit tip attachment techniques. Each CO-RE disposable tip has a circular groove inside the attachment orifice. An o-ring on the pipetting channel is expanded to fit this groove precisely providing an air-tight seal and straight alignment between tip and pipetting channel.

The amyloid beta peptide is derived from the cleavage of the Amyloid precursor protein (APP) and varies in length from 39 to 43 amino acids. However, the form(s) of amyloid-beta peptide (Aβ) associated with the pathology characteristic of Alzheimer’s disease (AD) remains unclear. In particular, the neurotoxicity of intraneuronal Aβ accumulation is an area of considerable research and controversy principally because antibodies thought to be specific for Aβ have been shown to actually detect intraneuronal APP and not Aβ exclusively. MOAB-2 (mouse IgG2b) is a pan-specific, high-titer antibody to Aβ residues 1-4 as demonstrated by biochemical and immunohistochemical analyses (IHC), and is highly specific just to amyloid beta peptide. MOAB-2 did not detect APP or APP-CTFs in cell culture media/lysates (HEK-APPSwe or HEK APPSwe/BACE1) or in brain homogenates from transgenic mice expressing 5 familial AD (FAD) mutation (5xFAD mice). Using IHC on 5xFAD brain tissue, MOAB-2 immunoreactivity co-localized with C-terminal antibodies specific for Aβ40 and Aβ42. MOAB-2 did not co-localize with either N- or C-terminal antibodies to APP. In addition, no MOAB-2-immunreactivity was observed in the brains of 5xFAD/BACE-/- mice, although significant amounts of APP were detected by N- and C-terminal antibodies to APP, as well as by 6E10. In both 5xFAD and 3xTg mouse brain tissue, MOAB-2 co-localized with cathepsin-D, a marker for acidic organelles, further evidence for intraneuronal Aβ, distinct from Aβ associated with the cell membrane. MOAB-2 demonstrated strong intraneuronal and extra-cellular immunoreactivity in 5xFAD and 3xTg mouse brain tissues.

L-Histidine has been used to study cultures of the human T-lymphoblastic leukemia cell line MOLT-4 to study modulation of apoptosis. Exogenous histidine has been shown to enhance the biosynthesis of lovastatin by cultured Aspergillus terreus. Histidine has been utilised as a single nitrogen source to probe swarming in Pseudomonas aeruginosa on agar. An in vivo study has used L-histidine to diminish the net secretory response of the small intestine of of cholera toxin-challenged mice.
