Description

Brucella abortus is an intracellular, blood-borne parasite. It is a Gram-negative coccobacillus that causes an infectious and contagious disease called Brucellosis. The disease primarily affects cattle but it can also be transmitted to humans from infected animals and consuming their products. The disease can lead to great economic loss especially in the dairy and agricultural industry. The Brucella abortus genome contains two DNA chromosomes in a circular confirmation; the first chromosome is approximately 2.1 Mb and the second chromosome is approximately 1.2Mb. Unusually it does not contain any plasmids or genomic islands that relate to pathogenicity and lacks many other genes that code for common virulence factors including capsules, fimbriae, exotoxins, cytolysins, resistance forms, or antigenic variation. The most common mode of transmission to humans is through the ingestion of unpasteurized milk and cheese products as the bacteria are present in the milk glands of infected female cows. In cattle transmission can also be through ingestion but in addition, the bacteria can persist in the reproductive tracts of males, namely seminal vesicles, ampullae, testicles, and epididymides, allowing sexual transmission. In humans the bacteria enter macrophages by phagocytosis and then live in compartments of vacuolar space along the endoplasmic reticulum. They persist by inhibiting host apoptosis and go onto form chronic disease causing lesions in the liver, spleen, bone marrow and kidneys. In cattle the bacteria additionally infect the trophoblast epithelial cells, which provide nutrition to the embryo. The trophoblast cells eventually lyse, releasing further bacteria into the blood stream of the embryo. The B. abortus cells in the blood stream go on to colonize the placenta and fetus in pregnant female cows, resulting in abortion of the fetus. Abortion can also result from insufficient anti-Brucella activity in the amniotic fluid. In humans, the disease can be either acute or chronic and some of the symptoms include fluctuating fever, chills, sweating, headache, muscle pain and weight loss. Once a person becomes infected they are prescribed a combination of tetracycline and streptomycin for 3-6 weeks. In cattle, additional symptoms include arthritic joints and retained after-birth.

Overview

• Isolate high quality, high yield plasmid DNA
• Plasmid DNA is ready for various downstream applications including restriction digestion, bacterial transformation, sequencing and more
• Available in 4 formats: MiniPrep, MiniPrep (Magnetic Bead System), 96-Well MiniPrep (Magnetic Bead System), and MaxiPrep

These kits are designed for the rapid preparation of plasmid DNA from Escherichia coli.

Plasmid MiniPrep Kit

This kit is designed for the rapid preparation of plasmid DNA from small cultures of Escherichia coli using convenient spin columns. The plasmid DNA is preferentially purified from other cellular components such as genomic DNA and RNA. This kit is able to purify plasmids up to 13,000 bp in size, and the typical purification yield is up to 20 μg from 1.5 mL of bacterial culture. Purified DNA is of excellent quality for transformation, restriction enzyme digestion, sequencing and more. Also available in a 96-well format.

Plasmid MiniPrep Kit (Magnetic Bead System and High Throughput Magnetic Bead System)

Norgen’s Plasmid MiniPrep Kit (Magnetic Bead System) is designed for the rapid preparation of plasmid DNA from small batch cultures of Escherichia coli. Norgen’s magnetic beads bind DNA under optimized salt concentrations and release the bound DNA under low salt and slightly alkali conditions. The plasmid DNA is preferentially purified from other cellular components such as genomic DNA and RNA. The purified plasmids are fully digestible with all restriction enzymes tested, and are completely compatible with real-time PCR and NGS.

Norgen’s Plasmid MiniPrep Kit (Magnetic Bead System) is also available in a 96-well (HT) format for high throughput applications. Purification with the 96-well plates can be integrated with a robotic automation system.

Plasmid MaxiPrep Kit

This kit is designed for the rapid spin column preparation of plasmid DNA from up to 100 mL of Escherichia coli cultures. The kit allows for the isolation of plasmid DNA with final endotoxin levels of 0.1 EU/µg of DNA or less. The kit is able to purify plasmids up to 13,000 bp in size, and typical yields from a 100 mL culture for a high copy number plasmid are between 0.4 and 1.0 mg. The purified DNA is fully digestible with all restriction enzymes tested, and is completely compatible with manual or automated sequencing to achieve 95-100% accuracy.

Overview

Optically clear adhesive film with pressure activated adhesive. Seal is peelable; suitable for qPCR and other imaging techniques including crystallization.

• Optically clear seal specifically developed for optical applications, particularly qPCR
• It is non sticky when removed from the packaging; this aids handling when wearing gloves
• The adhesive is contained within small capsules, allowing light to pass through to ensure the optical clarity of the seal
• When the seal is in position, pressure can be applied to burst the capsules, releasing a strong adhesive only where the seal touches the raised well rims of the plate – the rest of the seal area above the wells remains optically clear
• For all adhesive seals, the best sealing results are achieved using our Hand Roller or KAPS 500 Auto Sealer
