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 infection of various bacteria. Streptococcus dysgalactiae, a Lancefield group C α-hemolytic gram-positive bacteria, is a common pathogen in subclinical and clinical mastitis causing substantial economic losses in dairy herds. Streptococcus dysgalactiae has been isolated from infected mammary glands and teat injuries and is transmitted primarily during milking. However, detection of S. dysgalactiae in other cow tissues such as tonsils, mouth and vagina, and occurrence of S. dysgalactiae mastitis during the non-lactating period in herds, suggests that the organism also behaves as an environmental pathogen.

NH-bis(PEG4-Propargyl) is a bifunctional PEG compound containing two terminal alkynes that are joined together at a secondary amine. Terminal alkynes are reactive towards azides in copper (I) click chemistry to form stable triazoles with the target compound. The secondary amine joining the two arms can be used as a nucleophile such as in alkylation via reductive amination or in forming amides with carboxylic acids or activated NHS esters. The use of a central amine also allows for hydrogen bonding, further increasing this compound’s water solubility.

This product is based on silica Column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mm Tris,pH9.0, 0.5mm EDTA).

Storage and Stability
Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15–25°C) and are stable for at least 18 months under these conditions. Buffer ATL may precipitate at low temperature. Dissolve it by 37℃ water bath.
