Research Products International Corp RPI Cefuroxime, Sodium Salt, 25 Grams

Cefuroxime Sodium Salt is a second-generation cephalosporin antibiotic. Cefuroxime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). This interference disrupts the final stages of peptidoglycan synthesis in the bacterial cell wall, leading to structural instability and eventual cell lysis.

Cefuroxime is effective against a wide spectrum of bacteria, both Gram-positive and Gram-negative. In microbiology and research settings, it is sometimes used as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Additionally, Its inclusion allows for the specific growth of bacteria lacking resistance to cefuroxime.

AG Scientific Inc Tetracycline HCl 25 G

Tetracycline hydrochloride is a hydrochloride salt form of the antibiotic tetracycline. This polyketide antibiotic binds to both the 30S and 50S ribosomal subunits, thus inhibiting proper protein synthesis. Although it is capable of binding to both subunits, the binding at the 30S subunit is more pronounced than that at the 50S.Clinically, tetracycline is used as a broad spectrum antibiotic for a variety of Gram-positive and Gram-negative bacterial infections. Conditions which may indicate for tetracycline administration include upper respiratory infection, typhus fever and rikkettsialpox. It can also be administered to treat severe cases of acne.Tetracycline has played a prominent research role in studies of the efficacy of local antibiotic application in cases of dental trauma. Owing to the fluorescent properties of tetracycline and its ability to bind to bone tissue, this antibiotic is also regularly used in bone histomorphometry studies.

AG Scientific Inc Hygromycin B in Water, 10 ML

The concentration of Hygromycin B in DI water is 100mg/ml. Hygromycin B is an aminoglycoside antibiotic effective against bacteria, fungi, and eukaryotic cells that are isolated from Streptomyces hygroscopicus. It is composed of amino groups attached to glycosides, that bind the 30s ribosomal subunits. This action causes the mRNA sequence to be misread, resulting in protein synthesis inhibition. Hygromycin B is also an antiviral agent, which works as a standard section antibiotic in gene experiments.CAS Number: 31282-04-09Molecular Weight: 527.5 DaChemical Formula: C20H37N3O13Storage Temperature: +4CResearch or further manufacturing use only, not for food or drug use.

Apexbio Technology LLC Anisomycin 22862-76-6 10mM (in 1mL DMSO)

Anisomycin is an activator of c-Jun N-terminal kinase (JNK) a stress-activated protein kinase implicated in apoptotic signaling pathways regulating cell proliferation cell cycle progression and apoptosis It activates the JNK pathway at approximately 25 ng/ml concentration Experimental studies demonstrate anisomycin s capability to sensitize apoptosis-resistant cancer cell lines such as DU145 prostate carcinoma cells to Fas-mediated apoptosis as well as to induce apoptosis in leukemic HL-60 cells and primary mouse embryonic fibroblast cells by initiating JNK activation Anisomycin is thus widely utilized as a molecular tool in apoptosis-related research and insight into JNK-associated cell signaling

Apexbio Technology LLC CCCP,500mg CAS# 555-60-2

CCCP (carbonyl cyanide m-chlorophenyl hydrazine) is widely used uncoupler of oxidative phosphorylation.The uncoupler of oxidative phosphorylation blocks ATP synthesis by collapsing the proton motive force.In vitro: A genetic β-galactoside reporter system with a disk diffusion assay on MacConkey Lactose agar petri plates to monitor maintenance of the bacteriophage λ prophage state and viral induction in Escherichia coli K-12. It presented evidence that the phage λ major lytic promoters, pL and pR, are activated via cells containing the reporters following exposure to the energy poison CCCP. Requirement of expression of the λ lytic promoters in response to CCCP is host RecA function and an auto-cleavable CI repressor, as does SOS induction of the λ prophage occurring by a DNA damage-dependent pathway. CCCP-mediated activation of the λ lytic promoters required λ Cro function. CCCP does not modulate an sfi-lacZ SOS reporter [1]. Other sizes are also available. Please inqury us for quote.
