Apexbio Technology LLC Cromolyn sodium 15826-37-6 1g
Cromolyn sodium (CAS 15826-37-6) is a small molecule that functions as a mast cell membrane stabilizer It inhibits antigen-induced histamine release by preventing degranulation of sensitized mast cells Due to minimal gastrointestinal absorption cromolyn sodium is typically administered via inhalation in powder form Preclinical studies have demonstrated that cromolyn sodium suppresses both immediate and late-phase asthmatic responses and reduces the release of non-histamine chemical mediators Additionally it prevents ciliary transport impairment associated with bronchial provocation and can mitigate symptoms in exercise-induced asthma models These properties make cromolyn sodium a useful tool for investigating allergic and inflammatory mechanisms in respiratory research
Apexbio Technology LLC Hematoxylin 517-28-2 1g
Hematoxylin (CAS 517-28-2) is a naturally derived dye obtained from the heartwood of Haematoxylum campechianum Upon oxidation hematoxylin forms a quinone structure that complexes with metal ions such as aluminum or iron producing a cationic dye-metal complex This complex preferentially binds to basophilic cellular components particularly nucleic acids within cell nuclei resulting in prominent nuclear staining Hematoxylin is most commonly applied in combination with eosin in H E staining protocols facilitating differentiation of nuclear and cytoplasmic structures in histological and pathological tissue analysis
Apexbio Technology LLC Risedronate Sodium 115436-72-1 1g
Risedronate Sodium (115436-72-1) is a small-molecule inhibitor targeting farnesyl diphosphate (FPP) synthase It is designed to block FPP synthase thereby interfering with the mevalonate pathway and decreasing downstream protein prenylation necessary for cellular proliferation and survival Risedronate Sodium exerts its biological activity primarily through inhibition of FPP synthase leading to antiproliferative and proapoptotic effects in multiple tumor cell lines Additionally it modulates bone metabolism by suppressing osteoclast-mediated bone resorption Based on these pharmacological properties Risedronate Sodium holds research potential in tumor cell biology apoptosis pathways osteoporosis and metabolic bone disease models
Apexbio Technology LLC Sulforhodamine B sodium salt 3520-42-1 1g
Sulforhodamine B sodium salt (CAS 3520-42-1) is a fluorescent dye used for quantification of total cellular protein Sulforhodamine B sodium salt functions by electrostatically binding to cellular protein residues In cell-based studies fluorescence intensity after washing off unbound dye reflects the protein content of cultured cells This principle is applied for protein quantification assays including cytotoxicity assessments and cell proliferation assays Based on these properties Sulforhodamine B sodium salt is utilized in cell biology and biomedical research applications

Apexbio Technology LLC Amikacin 37517-28-5 1g
Amikacin (CAS 37517-28-5) is a small-molecule inhibitor targeting the bacterial 30S ribosomal subunit It is designed to interfere with protein synthesis thereby disrupting bacterial growth Amikacin exerts its biological activity primarily through specific binding to the 30S ribosomal subunit leading to inhibition of bacterial protein synthesis In in vitro studies Amikacin demonstrates antibacterial activity with reported IC50 values ranging from approximately 2 to 16 g/mL depending on bacterial species strain variations and assay conditions Based on these pharmacological properties Amikacin holds research potential in bacterial resistance studies antibiotic pharmacodynamics and antimicrobial susceptibility testing
Apexbio Technology LLC L-Phenylephrine 59-42-7 1g
L-Phenylephrine (CAS 59-42-7) is a selective agonist of the adrenergic 1A receptor exhibiting a Ki of 1 4 M with markedly lower affinity for 1B (Ki 23 9 M) and 1C (Ki 47 8 M) subtypes In vitro L-Phenylephrine has been shown to reduce apoptosis in neonatal rat cardiomyocytes following hypoxia and serum deprivation and to stimulate proliferation in neural progenitor cells It also increases the cross-sectional area and modulates gene expression in rat neonatal cardiomyocytes In vivo local administration in rats induces cutaneous anesthesia through 1-adrenergic receptor activation and clinical data suggest oral administration reduces nasal airway resistance These properties make L-Phenylephrine a valuable tool for studying 1A-adrenergic receptor-mediated cellular responses
