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 Nilotinib monohydrochloride monohydrate 923288-90-8 1g
Nilotinib monohydrochloride monohydrate (CAS 923288-90-8) is a selective small molecule inhibitor targeting the BCR-ABL tyrosine kinase By binding to the ATP-binding site of BCR-ABL nilotinib effectively suppresses kinase activity impeding downstream signaling involved in cell proliferation It demonstrates potent inhibitory activity with an IC50 below 30 nM Nilotinib is widely utilized in biomedical research to investigate BCR-ABL-mediated cellular mechanisms and to model therapeutic interventions in chronic myelogenous leukemia and related malignancies
Apexbio Technology LLC Ofloxacin 82419-36-1 1g
Ofloxacin (CAS 82419-36-1) is a small-molecule inhibitor targeting bacterial DNA gyrase (topoisomerase II) and topoisomerase IV It is designed to inhibit these enzymes thereby blocking bacterial DNA replication and transcription Ofloxacin exerts its biological activity primarily through disruption of DNA supercoiling by binding to the enzyme-DNA complex preventing proper DNA synthesis and bacterial proliferation In in vitro studies ofloxacin demonstrates inhibitory activity with reported IC50 values ranging from 0 5 to 10 g/mL depending on bacterial strain variability and experimental conditions Based on these pharmacological properties ofloxacin holds research potential in microbiological and pharmaceutical studies such as bacterial resistance research evaluation of bacterial enzyme inhibition susceptibility assay validation and investigation of bacterial gene regulation and replication mechanisms
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 Rhodamine B 81-88-9 1g
Rhodamine B (81-88-9) is a synthetic fluorescent dye Its molecular structure enables excitation at specific wavelengths and emission of detectable fluorescence signals Rhodamine B is widely applied as a labeling agent in microscopy-based analyses facilitating visualization for intracellular labeling and tracking Researchers use Rhodamine B to stain cellular structures assess membrane permeability and monitor interactions of biomolecules such as proteins and nucleic acids Fluorescence intensity changes also support assays investigating enzyme activity apoptotic processes and intracellular uptake Based on these properties Rhodamine B holds research potential in cellular imaging biomolecular tracking and pharmaceutical distribution studies
