N-(Amino-PEG4)-N-bis(PEG4-propargyl) HCl salt

Overview

• Quantified standard to be used as a positive control or PCR quantification standard
• Vigorously quantified using multiple methods

Mastitis is the single most costly disease of dairy cattle resulting in the reduction of milk yield and quality. The inflammation of the utter is mainly caused by bacteria, and Staphylococcus aureus (S. aureus) is often considered the most common cause of contagious mastitis in dairy herds. S. aureus infection is estimated to be present in up to 90% of dairy farms and is responsible for 35% of the economic loss in the dairy industry. S. aureus is a facultatively anaerobic, Gram positive bacterium. The majority of S. aureus strains are catalase-positive and coagulase-positive, which forms the basis of traditional identification methodology.

Staphylococcus aureus Quantified Bacterial DNA Standard is prepared from cultured bacteria using Norgen’s sample preparation technology. The purified DNA is quantified vigorously using multiple methods including spectrophotometry, gel densitometry and real-time PCR. It is intended to be used as a positive control or PCR quantification standard for Staphylococcus aureus.

Storage Conditions

Upon receipt, store Norgen’s Staphylococcus aureus Quantified Bacterial DNA Standard at -20^oC or lower. Avoid multiple freeze-thaw cycles. If needed, prepare smaller working aliquots and store at -20^oC or lower.

Propargyl-PEG3-bromide comprises a propargyl group and a bromide group. The propargyl group reacts with azide-bearing compounds or biomolecules in Click Chemistry to yield a stable triazole linkage; copper will be needed as a catalyst. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
