Cefetamet-d3
Cefetamet-d3 (Ro 15-8074-d3; Deacetoxycefotaxime-d3) is the deuterium labeled Cefetamet (HY-A0111). Cefetamet (Ro 15-8074) is a cephalosporin antibiotic and the active metabolite of Cefetamet pivoxil (HY-B1894A). Cefetamet binds to bacterial penicillin-binding protein (PBP) (IC50 for PBP3 in Escherichia coli W3110 is 2.5 μg/mL). Cefetamet has significant activity against Gram-negative bacteria such as Enterobacteriaceae, Neisseria species, and Haemophilus influenzae, as well as Gram-positive bacteria such as Streptococcus. Cefetamet kills and lyses Treponema pallidum. Cefetamet can be used in the research of respiratory tract, urinary tract, ear, nose and throat infections, and syphilis.

In Vitro
Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. Further protocols information, click here.

Gram Staining of Tissue Sections
Gram staining of tissue sections is a histochemical technique used to differentiate Gram-positive and Gram-negative bacteria within histological specimens based on differences in bacterial cell wall structure and dye retention, adapted from classical bacteriological Gram staining into tissue-compatible “histological Gram stain” variants. In tissue applications, modifications of the Brown-Hopps and Brown-Brenn methods are commonly used to improve differentiation of microorganisms embedded within host connective tissue and to reduce overstaining or loss of Gram-negative signal, which are known limitations of earlier approaches. The principle relies on crystal violet-iodine complex retention in Gram-positive organisms and subsequent decolorization and counterstaining steps that allow contrast visualization of Gram-negative organisms against tissue background.
