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.
Upon receipt, store Norgen’s Staphylococcus aureus Quantified Bacterial DNA Standard at -20oC or lower. Avoid multiple freeze-thaw cycles. If needed, prepare smaller working aliquots and store at -20oC or lower.
Sequentially purify total RNA (and miRNA), DNA and proteins from a single sample
No sample splitting or need to use phenol or precipitation methods
Purify RNA/DNA/Protein from cultured animal cells, tissues, blood, bacteria, yeast, fungi or plants
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
RNA/DNA/Protein Purification Plus Kit
This kit provides a rapid method for the high throughput isolation and purification of total RNA, DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, blood, bacteria, or yeast. The kit employs two columns: 1) for gDNA purification and 2) for RNA purification utilizing Norgen’s resin columns (superior for the binding of all RNA sizes including miRNA). The proteins are also purified on the second column after RNA elution. The proteins are eluted in buffer and are ready for downstream application without any further clean up required. The proteins can be quantified directly, used in western blots, ELISA or mass spectrometry. This kit provides a rapid spin-column method for the isolation and purification of total RNA, genomic DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, blood, bacteria, yeast, fungi or plants.
RNA/DNA/Protein Purification Plus Micro Kit
This kit provides a rapid spin-column method for the isolation and purification of total RNA, DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, microdissected samples including LCM, stem cells, sorted cells, and CTC. The total RNA, genomic DNA and proteins are all column purified in less than 30 minutes. The RNA and DNA can be eluted in as little as 20 µL while the protein can be eluted in as little as 50 µL. This kit provides the same performance as if the samples were isolated from dedicated kits.
RNA/DNA/Protein Purification 96-Well Plus Kit
The kit employs two plates: 1) for DNA purification and 2) for RNA purification utilizing Norgen’s resin (superior for the binding of all RNA sizes including miRNA). Please see the protocol schematic below.
DBCO-PEG24-Maleimide is a PEG linker containing a DBCO moiety and a terminal primary maleimide group. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
