Norgen’s Low Abundance DNA Quantification Kit offers a PCR-based detection procedure to quantify DNA of a wide spectrum of concentrations, including the lower ng per µL, pg per µL and sub-pg per µL range. The kit consists of a specially designed primer mix, that is used in conjunction with the provided 2x PCR Master Mix, to amplify human DNA from different types of inputs (such as various liquid biopsies). The kit is compatible with any Real-Time PCR system with the addition of fluorescent nucleic acid stains such as SYBR Green. The unknown DNA is accurately quantified by using a standard curve constructed from the provided DNA Standard.

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 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 (Lee et al., 2005). S. aureus is a facultatively anaerobic, Gram positive bacterium. The majority of S. aureus strains are catalase-positive and coagulasepositive, which forms the basis of traditional identification methodology.
