Thiobarbituric acid (TBA) reaction has been used to detect lipid oxidation. When lipids are oxidized, malonaldehyde is formed. TBA reacts with malonaldehyde in hot acid to form a red complex of malonaldehyde:TBA (1:2). Used to quantitate lipopolysaccharides, carrageenan, and sialic acids; used…

The molecule is a dialdehyde, consisting of two formyl (CHO) groups attached to adjacent carbon centres on a benzene ring. o-Phthalaldehyde is used for precolumn derivatization of amino acids for HPLC separation and for flow cytometric measurements of protein thiol groups. Used for fluorometric…

Diphenylcyclopropenone is a potent hapten. Its vibration frequency has been evaluated. Diphenylcyclopropenone was used in topical immunotherapy.

Stem Cell Factor (SCF) is a hematopoietic growth factor that exerts its activity at the early stages of hematopoiesis. SCF stimulates the proliferation of myeloid, erythroid, and lymphoid progenitors in bone marrow cultures and has been shown to act synergistically with colony stimulating factors.…

Lactic acid is fermentation acid from milk or carbohydrates. It occurs in the blood and muscle fluid of man and animals. The lactic acid concentration increases in muscle and blood after vigorous activity. It is also present in other organs including liver, kidney, and thymus gland, and other body…

Cyclophosphamide monohydrate is an alkylating, antineoplastic agent, which is converted in the body to an active alkylating metabolite (4-hydroxycyclophosphamide). It possesses immunosuppressant properties. Cyclophosphamide monohydrate used for induction chemotherapy to study predictive and…

Brefeldin A is a fungal metabolite which is a macrocyclic lactone exhibiting a wide range of antibiotic activity. Produced by Penicillium brefeldianum. Blocks binding of the cytosolic coat protein b-COP and ARF to Golgi membranes mediated by protein G. Also blocks protein transportation into…

Squalene, an isoprenoid compound structurally similar to beta-carotene, is an intermediate metabolite in the synthesis of cholesterol. Squalene is not very susceptible to peroxidation and appears to function in the skin as a quencher of singlet oxygen, protecting human skin surface from lipid…
