Cefotaxime sodium salt ≥95%, off-white powder

Supplier: MP Biomedicals
Description: Cefotaxime is a cephalosporin, which acts by interference of synthesis of peptidoglycan of the bacterial cell wall. Cefotaxime, a cephalosporin antibiotic, is active against both gram-negative and gram-positive bacteria. In addition, cefotaxime blocks the division of cyanobacteria and lower plant organelles/plastids such as the photosynthetic organelles of Glaucophytes and chloroplasts of bryophytes.
Cefotaxime is used for infections of the respiratory tract, skin, bones, joints, urogenital system, meninges, and bloodstream. It generally has good coverage against most Gram-negative bacteria, with the notable exception of Pseudomonas. It is also effective against most Gram-positive cocci except for Enterococcus. It is active against penicillin-resistant strains of Streptococcus pneumoniae. It has modest activity against the anaerobic Bacteroides fragilis. In meningitis, cefotaxime crosses the blood–brain barrier better than cefuroxime.
Cefotaxim inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. As a result, bacteria lyse due to cell wall autolytic enzymes.

Disposable particle filtering respirators, FFP2/FFP3 Smart Series®

Supplier: Moldex
Description: These masks provide protection against fine toxic dust, oil and water-based mists and fumes. Due to the DuraMesh® structure, Moldex masks are strong and durable, thus reducing consumption. The ActivForm® seal automatically adjusts to different face types and their movements. The masks have passed the optional Dolomite clogging test and therefore ensure better breathing resistance.

β-Nicotinamide adenine dinucleotid, oxidised form (NAD, oxidised form) ≥98%, white powder cell culture reagent

Supplier: MP Biomedicals
Description: Storage: -20°C, desiccate
This is an ultrapure NAD, chromatographically purified to remove trace inhibitors.
β-NAD, a pyridine nucleotide and biologically active form of nicotinic acid, is a coenzyme necessary for the catalytic reaction of certain enzymes. It occurs in living cells primarily in the oxidized state. Serves as a coenzyme of the dehydrogenases, especially in the dehydrogenation of primary and secondary alcohols. NAD usually acts as a hydrogen acceptor, forming NADH which then serves as a hydrogen donor in the respiratory chain.
Many metabolites and enzymes of biological interest are present in tissues at low concentrations. With the use of β-NAD as a catalyst intermediate and several enzymes in a multistep system, known as enzyme cycling, much greater sensitivity for detection of these components is achieved. The reduced form, β-NADH, is fluorescent whereas β-NAD is not. This difference in fluorescence provides a sensitive fluorescent measurement of the oxidized or reduced pyridine nucleotides at concentrations down to 10-7 M.
Electron acceptor. β-NAD is a carrier for hydride ion, forming b-NADH. Hydride ion is enzymatically removed from a substrate molecule by the action of dehydrogenases such as malic dehydrogenase and lactic dehydrogenase. Such enzymes catalyze the reversible transfer of a hydride ion from malate or lactate to b-NAD to form the reduced product, b-NADH. Unlike b-NAD which has no absorbance at 340 nm, b-NADH absorbs at 340 nm (EmM = 6.22). The increase in absorbance at 340 nm with the formation of b-NADH is the basis for measurement of activity of many enzymes.

Neutrophil/Monocyte Respiratory Burst Assay Kit

Catalog Number: (CAYM601130-1)
Supplier: Cayman Chemical
Description: Neutrophil/Monocyte Respiratory Burst Assay Kit provides PMA, dihydrorhodamine 123, and additional reagents necessary for inducing and quantifying a respiratory burst response in neutrophils and monocytes by flow cytometry. The assay can be performed on whole blood or on cells in various types of cell culture media. Because the assay reagents are not species-specific, this assay can be used in any species or cell type capable of producing a NADPH oxidase-dependent respiratory burst response.
