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 Sulfaphenazole 526-08-9 1g
Sulfaphenazole (CAS 526-08-9) is a small-molecule inhibitor targeting cytochrome P450 2C9 (CYP2C9) It is designed to selectively inhibit CYP2C9-mediated drug metabolism thereby informing metabolic pathway studies and investigation of drug-drug interactions Sulfaphenazole exerts its biological activity primarily through competitive inhibition of CYP2C9 In in vitro assays sulfaphenazole demonstrates potent inhibition with a reported Ki value of approximately 0 3 M for human CYP2C9 Based on these pharmacological properties sulfaphenazole holds research potential in evaluating CYP2C9-mediated metabolic processes and associated drug interactions

Apexbio Technology LLC Lamotrigine 84057-84-1 1g
Lamotrigine (CAS 84057-84-1) is a small molecule anticonvulsant that acts primarily as a voltage-gated sodium channel blocker stabilizing neuronal membranes and inhibiting repetitive neuronal firing Research indicates that lamotrigine inhibits serotonin (5-HT) uptake with reported IC50 values of 240 M in human platelets and 474 M in rat brain synaptosomes These dual actions on sodium channels and 5-HT transport underline its utility in studies investigating the modulation of excitatory neurotransmission and synaptic function in neurological and psychiatric conditions
