Anti-HIV Type-1 p24 Mouse Monoclonal Antibody [clone: HIV1-24/661]

Catalog Number: (PRSI33-250)
Supplier: ProSci Inc.
Description: Human immunodeficiency virus (HIV) is a retrovirus that causes acquired immune deficiency syndrome (AIDS), a condition in humans in which the immune system begins to fail, leading to life-threatening opportunistic infections. HIV mainly infects vital cells in the human immune system such as helper T cells (specifically CD4+ T cells), macrophages and dendritic cells. Two species of HIV infect humans: HIV-1 and HIV-2, with HIV-1 being the more virulent strain. The gag gene of human immunodeficiency virus 1 (HIV-1) encodes a precursor protein known as Pr55Gag. The viral protease PR cleaves this precursor to generate p17, p24, p7, and p6 proteins, which are required for virus particle assembly. HIV-1 Gag p24 is a capsid protein that constitutes the core of AIDS virus HIV-1. p6 and p7 are the components of the nucleocapsid, and p17 provides a protective matrix. HIV-1 Gag p24 is indispensable to the reproduction of AIDS virus and constitutes an essential element for the AIDS virus particle construction. As this protein is detectable from the early stage of AIDS virus infection, its measurement is commonly used as an indicator of HIV-1 infection and viral load.

Anti-GFP Mouse Monoclonal Antibody

Catalog Number: (PRSI32-160)
Supplier: ProSci Inc.
Description: GFP (Green fluorescence protein) is a 27 kDa protein derived from the jellyfish Aequorea victoria, which emits green light when excited by blue light. GFP cDNA produces a fluorescent product when expressed in prokaryotic cells, without the need for exogenous substrates or cofactors. GFP has become an invaluable tool in cell biology research, since its intrinsic fluorescence can be visualized in living cells. GFP fluorescence is stable under fixation conditions and suitable for a variety of applications. GFP has been widely used as a reporter for gene expression, enabling researchers to visualize and localize GFP-tagged proteins within living cells without the need for chemical staining. Other applications of GFP include assessment of protein protein interactions through the yeast two hybrid system and measurement of distance between proteins through fluorescence energy transfer (FRET) protocols. GFP technnology has considerably contributed to a greater understanding of cellular physiology.

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.

Test kits, photometric, Surfactants, anionic, LCK cuvette tests

Catalog Number: (HACHLCK432)
Supplier: Hach
Description: The standard anionic surfactant method has several drawbacks:
*Multiple handling steps are time consuming and complicated.
*Large volumes of extraction solvents create a safety and environmental risk.
*The combination of lengthy handling time, glassware maintenance, and solvent disposal adds up to significant costs per test. A standardised cuvette-based extraction and photometric measurement system overcomes all these disadvantages to provide accurate, reproducible results.
