DBCO-PEG23-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydrophilic PEG spacer increases the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Carbendazim is a fungicide used for the treatment and control of fungal diseases. Carbendazim continues to be used, frequently in combination with other fungicides.
This kit is based on ELISA technology, which is fast, easy, accurate and sensitive compared with common instrumental analysis and only needs 1.5 hours in one operation, it can considerably minimize operation error and work intensity.
Usages: For isolation and enumeration of coagulase-positive staphylococci in foodstuffs.
Principle: Tryptone, beef extract powder and yeast extract powder provides carbon and nitrogen sources, vitamins and growth factors; sodium pyruvate and glycine to stimulate the growth of Staphylococcus aureus; lithium chloride and potassium tellurite inhibit the non-staphylococcal microorganisms; containing lecithinase staphylococcal colonies produce degradation yolk make transparent circle, while the role of the lipase produced an opaque precipitate ring; coagulase-positive staphylococci can restore potassium tellurite and produce black colonies; agar is medium coagulant.
Formulation(per liter): Pancreatic Digest of Casein 10g Beef Extract 5g Yeast Extract 1g Sodium Pyruvate 10g Glycine 12g Lithium Chloride 5g Agar 20g Final pH7.0 ± 0.2
How to use: 1.Suspend 63g in 950ML of distilled water , stirring heated to boiling ,autoclave at 121℃ for 15 minutes. 2.Diluted and treated samples.
