DBCO-PEG4-NHS Ester is a click chemistry PEG reagent containing NHS ester that is able to react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Overview
Detection kits for the HBV
Available in TaqMan format for analysis
The Hepatitis B virus (HBV) is mainly transmitted via blood or blood products. In addition, sexual, oral and perinatal infections are also possible. Early symptoms of the infection include appetite loss, vomiting and abdominal symptoms, with approximately 10-20% of those patients developing fever as well as rheumatoid joint and muscle pain. Jaundice, which may be accompanied by itching, will then develop within 2-14 days. Fulminant hepatitis then occurs in about 1% of all infected patients, which in severe cases may be fatal. Of those individuals infected by HBV, 5-10% will develop chronic liver inflammation which may progress to cirrhosis of the liver or, in the worst case, primary liver cell carcinoma. The HBV virus is a hepadnavirus that has a circular genome composed of partially double-stranded DNA.
HBV TaqMan PCR Kit, 100 reactions
Ready to use format, including Master Mix for the target and PCR control to monitor for PCR inhibition and validate the quality
Specific Primer and Probe mix for the pathogen/virus/viroid of interest
Primer and Probe mix
Positive and negative control to confirm the integrity of the kit reagents
HBV TaqMan PCR Probe/Primer Set and Controls, 100 reactions
Specific Primer/Probe mix and Positive Control for the pathogen/virus/viroid of interest
Nuclease-free water
Can be used together with Norgen’s PCR Master Mix (#28007) or customer supplied master mix
For research use only and NOT intended for in vitro diagnostics.
Storage Conditions and Product Stability All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
Purify amplified DNA ranging from 100 bp -15,000 bp in size
Fast and efficient spin column format
Available in a 50 prep size and a 250 prep size
Also available in 96 well format
This kit enables the rapid purification of amplified DNA products from PCR mixes. It is able to effectively remove PCR by-products including primers, dimers, enzymes, unincorporated nucleotides and mineral oil from the desired PCR product. The purified PCR products are fully compatible with restriction enzyme digestion, ligation into vectors, labeling, sequencing and more. This kit can also be used as an alternative to organic extraction and ethanol precipitation to clean up various enzymatic reactions.
The kit is also available in a 96-well format for high-throughput PCR purification. Purification with the 96-well plate can be performed using either a vacuum manifold or centrifugation.
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 1 year after the date of shipment.
