Supplier: USP

USP Reference Standards are specified for use in conducting official USP–NF tests and assays. USP also provides Reference Standards specified in the Food Chemicals Codex as well as authentic substances—high-quality chemical samples—as a service to analytical, clinical, pharmaceutical and research laboratories. To confirm accuracy and reproducibility, USP Reference Standards are rigorously tested and evaluated by multiple independent laboratories including USP, commercial, regulatory, and academic labs. USP also provide publicly available, official documentary standards for pharmaceutical ingredients in the USP–NF that link directly with our primary reference standards.

Supplier: Restek

These columns are based on a wide pore material designed for optimal large-molecule separations. Base-deactivated, wide-pore packing exhibits excellent peak shape for a wide range of compounds. Less retention in reversed phase assays than Viva C18 or Viva C8.

The SER 148/3 and SER 148/6 can be used to separate a substance or a group of elements (e.g. fat) from solid and semi-solid samples according to the Randall technique (consisting of immersion, washing and solvent recovery). The main field of application is the determination of the content of soluble products such as fats, detergents, plasticisers and pesticides in food, animal feed, detergents, rubber and plastic formulas, pharmaceutical products, soil, and more.

Supplier: Merck

These columns have been designed following the high demand for suitable analytical methods for process monitoring and quality control of wide pore biomolecules. Accurate analysis of proteins, antibodies and large peptides requires columns with good permeability, along with better mass transfer and selectivity. In order for size exclusion not to influence the separation, the pore size should be approximately ten times larger than the molecule being analysed.

Supplier: MP Biomedicals

Bleomycin Sulfate is an atineoplastic antibiotic. A mixture of cytotonic glycopeptide antibiotics which reacts with DNA and causes strand scission; they have also been shown to have a type of oxygen transferase activity. Bleomycin A2 is the main component of the bleomycin employed clinically. Bleomycins differ from one another in the terminal amine and show varying biological activity.

Lipid peroxidation is a well-established mechanism of cellular injury in both plants and animals, and is used as an indicator of oxidative stress in cells and tissues. Lipid peroxides, derived from polyunsaturated fatty acids, are unstable and decompose to form a complex series of compounds. These include reactive aldehydes, of which the most abundant is malondialdehyde (MDA). Therefore, measurement of malondialdehyde is widely used as an indicator of lipid peroxidation. Increased levels of lipid peroxidation products have been associated with a variety of chronic diseases in both humans and model systems.
