Alkali Scientific Actinomycin D [Actinomycin C1] [Dactinomycin], 5 Milligrams

Actinomycin D is a potent transcription inhibitor widely used in molecular biology and cancer research. It binds to DNA at guanine cytosine rich regions, preventing RNA polymerase from progressing during transcription. This effectively blocks RNA synthesis and is commonly used to study gene expression, transcriptional regulation, and cellular responses to DNA damage. Actinomycin D is also used in apoptosis studies and cancer cell research due to its ability to interfere with rapidly dividing cells. Supplied in a 5 milligram quantity, it is suitable for highly controlled laboratory experiments requiring precise inhibition of nucleic acid synthesis.

Alkali Scientific Carbenicillin, Disodium Salt, 1 G

Carbenicillin Disodium Salt is a beta-lactam antibiotic used in microbiological research for its ability to inhibit bacterial cell wall synthesis. It interferes with the formation of peptidoglycan cross-links, leading to weakened cell walls and bacterial lysis. Carbenicillin is commonly used in molecular biology for the selection of plasmid-containing bacteria, particularly in cloning and transformation experiments. Compared to ampicillin, it offers improved stability and reduced satellite colony formation. This compound is widely applied in cell culture and microbiology laboratories for maintaining selective pressure in bacterial cultures and supporting studies involving gene expression, recombinant DNA technology, and antimicrobial activity.
