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.

Cesium chloride, an inorganic compound, is an important source of cesium ions in a variety of applications. Its crystal structure forms a major structural type where each cesium ion is coordinated by 8 chlorine ions. Cesium chloride occurs naturally in mineral waters and as an impurity in carnallite (up to 0.002%), sylvite and kainite. Less than 20 tonnes of CsCl is produced annually worldwide, mostly from a cesium-bearing mineral pollucite.

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.

Chlorhexidine digluconate, a bis(biguanide) family cationic broad spectrum antibiotic is an antiseptic and disinfectant agent. It is effective against a wide range of bacteria, some fungi and some viruses, and an agent for the prevention of gingivitis. Chlorhexidine digluconate solution inhibits oxygen utilization which leads to a reduction in bacterial ATP . Commercial ophthalmic products have used this agent to replace thimerosal as a preservative; however, it can cause skin irritation.

HQ-O Ready-To-Dilute (RTD) Stain Reagent is designed to label amyloid plaques in paraffin-embedded or freshly cut frozen tissue sections. As a fluorescent zinc chelator, HQ-O is unique as it takes advantage of the known presence of concentrated zinc in amyloid plaques. Studies with HQ-O revealed that fluorescent plaque-like structures are only seen when synthetic Aβx-42 is aggregated in the presence of zinc. Under blue light excitation, plaque structures appear bright green fluorescent in the brain parenchyma, correlating closely with plaque structures observed following Aβ antibody staining.

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.
