Apexbio Technology LLC Salbutamol Sulfate 51022-70-9 500mg
Salbutamol Sulfate (CAS 51022-70-9) is a short-acting selective 2-adrenergic receptor agonist widely employed in studies related to bronchial smooth muscle relaxation The compound exerts its pharmacological effects by selectively activating 2-adrenergic receptors leading to increased intracellular cyclic AMP and subsequent airway smooth muscle relaxation Research indicates that the R-enantiomer is primarily responsible for the observed physiological effects in guinea-pig skeletal muscle with minimal contribution from the S-enantiomer Salbutamol Sulfate is commonly utilized in biomedical research focused on asthma chronic obstructive pulmonary disease (COPD) and 2-receptor pharmacodynamics
Medchemexpress LLC Gentamicin (sulfate) | 1405-41-0 | MFCD00270181 | >80% | C24H55N7O11S3* | 1 G
Gentamicin sulfate is an aminoglycoside antibiotic that inhibits the growth of both gram-positive and gram-negative bacteria, and it also inhibits several strains of mycoplasma in tissue culture. It has been observed to inhibit DNase I with an IC50 of 0.57 mM.
- Inhibits gram-positive and gram-negative bacteria
- Inhibits mycoplasma in tissue culture
- More effective in vitro bacterial inhibitor than penicillin-streptomycin
- Nontoxic to tissue culture monolayers and does not inhibit virus replication
- Used as an additive in commercial mycology media
- Bactericidal for a wide range of organisms
- Stable at autoclave temperatures
- Improves survival and alters inflammatory profile in murine sepsis model
- Down-regulates proinflammatory cytokines, IL-6
Alkali Scientific Polymixin B Sulfate, 5 G
Polymyxin B sulfate is a powerful antibiotic in powder form, commonly used for treating gram-negative bacterial infections. It is primarily used in research settings to study antibacterial activity and to test antimicrobial efficacy. In this 5 g format, Polymyxin B sulfate is often utilized in microbiology laboratories for susceptibility testing, particularly against bacterial strains resistant to other antibiotics. The compound has a potent mechanism of action that disrupts bacterial cell membranes, making it effective against a variety of resistant pathogens. Researchers use it for evaluating bacterial resistance patterns and its effects on cell cultures. It is also used to create antibiotic solutions for further applications in clinical and laboratory settings.

Medchemexpress LLC Ammonium sulphate | 7783-20-2 | ≥99.0% | 132.14 | 1 G
Ammonium sulphate, ≥99.0%, AR is an inorganic sulfate salt primarily utilized in molecular biology. It serves various purposes, including protein precipitation, antibody separation, and enhancing antigen-antibody reactions. Additionally, it functions as a nitrogen source in plant fertilizers. The product exhibits developmental toxicity to freshwater snails but contributes to an increase in Anopheles africanus and Culex mosquito larvae populations in rice paddies. It also inhibits the conversion of glucose to ascorbic acid in plants.
- Utilized in molecular biology
- Employed for precipitating proteins
- Separates antibodies
- Enhances antigen-antibody reactions
- Serves as a nitrogen source in plant fertilizers
- Inhibits the conversion of glucose to ascorbic acid in plants
