Tunicamycin is a mixture of Tunicamycins A, B, C and D. It is a nucleoside antibiotic active in vitro against Gram-positive bacteria, yeasts, fungi, and viruses. Tunicamycin has been used to study the effect of N-linked glycosylation of human proton-coupled folate transporter (HsPCFT) in HeLa…

Mitomycin C is the most widely used of the Mitomycin antibiotics because it is the least toxic and with the most potent antitumor activity. Inhibitor of DNA synthesis, nuclear division, and cancer cells. Antibacterial to gram positive, gram negative, acid-fast bacilli. Mitomycin C…

Puromycin is an antibiotic of unique structure and biological activity. It is produced by fermentation using Streptomyces albo-niger. There are four aspects of puromycin's biological activity that are 1) antitumor effect; 2) nephrotoxic action; 3) inhibition of purine and/or protein synthesis…

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.…

Elastase is an enzyme from the class of proteases (peptidases) that break down proteins. It hydrolyzes peptide bonds, especially those adjacent to neutral amino acids. Hydrolyses elastin Digests hemoglobin, casein, and fibrin One unit will solublize 1 mg of elastin in 20 minutes at…

Phosphatidylserine is a phospholipid component, usually present on the cytosolic side of cell membranes by an enzyme called flippase. When a cell undergoes apoptosis, phosphatidylserine is no longer restricted to the cytosolic part of the membrane, but becomes exposed on the surface of the cell. …

Citrinin is a fungal metabolite found in moldy rice. Citrinin was used to evaluate toxicity of the mycotoxin citrinin using yeast ORF DNA microarray and Oligo DNA microarray.
