Methyltetrazine-PEG5-DBCO is a TCO reactive reagent with a DBCO group and water-soluble PEG spacer. This reagent can be used to convert azido-containing peptides or proteins into tetrazine-modified peptides or protein without catalyst or axillary reagents. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Clostridium difficile is rod-shaped, gram positive bacterium. It is the main causal agent of antibiotic-associated diarrhea and pseudomembranous colitis. The colonization of intestines by C. difficile is usually associated with the elimination of natural intestinal flora as a result of antibiotic application and is frequently reported in health care centers. While C. difficile infection could be severe and life-threatening, particularly among the elderly, many patients are asymptomatic making diagnosis challenging during outbreaks. The tradition method of detecting C. difficile infection is by cytotoxicity test of the toxin produced by the bacterium, but such protocols usually require extensive time before conclusion can be made.
Storage Conditions and Product Stability All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
For general bacterial culture, in particular for molecular biology experiments preservation and enrichment of E. coli.
Principle:
Peptone, yeast extract powder provide nitrogen, vitamins and growth factors; sodium chloride to maintain osmotic equilibrium; glucose as carbon source.

2.Diluted and treated samples.
Storage: Keep container tightly closed, store in a cool, dry place, away from bright light. Storage period of 3 years.
Mycoplasma is a common and serious contaminant of cell cultures. Mycoplasma is often not visible and does not respond to antibiotics, and therefore it is a major issue that requires monitoring and early detection. Up to 30% of cell cultures may be contaminated with Mycoplasmas, the main contaminants being the species M. orale, M. laidlawii, M. arginini and M. hyorhinis. These organisms produce a variety of effects on the infected cells in culture, including changes in metabolism growth, viability and morphology, thereby altering the phenotypic characteristics of the host cells. Therefore there is an absolute requirement for routine, periodic assays to diagnose possible Mycoplasma contamination of all cell cultures, particularly continuous or established cell lines.
