Alkali Scientific Sodium Diatrizoate Dihydrate, 100 G
Sodium Diatrizoate Dihydrate is an iodinated contrast agent used in medical imaging to enhance visibility of internal structures during diagnostic procedures such as X-rays and CT scans. Available in a 100-gram quantity, this compound is commonly used in angiography, urology, and gastrointestinal imaging, where high-quality contrast is required for accurate diagnosis. Sodium Diatrizoate works by absorbing X-rays, providing enhanced differentiation between soft tissues and blood vessels. It is essential in imaging centers and diagnostic laboratories, where it is used to achieve clear and precise images, aiding in the identification of various medical conditions.

Apexbio Technology LLC SGI-1027 1020149-73-8 10mM (in 1mL DMSO)
SGI-1027 (CAS 1020149-73-8) is a small-molecule inhibitor of DNA methyltransferases (DNMTs) exhibiting IC50 values of 12 5 M for DNMT1 8 M for DNMT3A and 7 5 M for DNMT3B It acts by competitively inhibiting the cofactor Ado-Met binding site rather than the DNA substrate site resulting in reduced DNMT activity and subsequent inhibition of DNA methylation SGI-1027 suppresses both mammalian and bacterial DNMTs affecting endogenous and recombinant forms In cancer cell models it induces demethylation of CpG islands in gene promoter regions leading to reactivation of silenced tumor suppressor genes such as P16 and TIMP3 and promotes DNMT1 degradation via the proteasome pathway SGI-1027 is utilized in epigenetics research to study DNA methylation dynamics and gene reactivation
