Propargyl-PEG6-NHS ester

Description 

Champion™ E. coli Transformation Kit provides an easy method for rapid preparation of chemically competent cells with high transformation efficiency from fresh culture, overnight culture, or even directly from bacterial colonies on the plate. The competent cell preparation method eliminates the requirement of time-wasting wash step. In addition, preparation of competent cells from overnight culture or directly from bacterial colonies provides flexibility to cloning experiment. The resultant competent cells can be immediately used or stored at -70°C for one year. This kit includes a specialized SMO-Broth™ medium and a unique Champion™ CC Buffer for culturing and preparing competent cells efficiently. Following the simple and quick competent cell preparation protocol from fresh culture, the transformation efficiency is typically ranged from 10⁸–10⁹ cfu/μg transformants/μg of pUC19 plasmid DNA, but varies depending on the E. coli strains. The resultant competent cells can be further transformed using time-saving transformation protocol, eliminating the requirement of heat-shock and recovery steps. 

Features

• Flexible– fresh culture, overnight culture, 4°C stored liquid culture or even colonies on agar plate can be used for transformation. 
• Fast and Easy– only few steps for preparation; suitable for time-saving transformation 
• High efficiency– up to 109 cfu/μg 
• Personalization– suitable for most E. coli strains

Description

Our SNPsig® kits use our own proprietary genotyping method to enable the identification of SARS-CoV-2 variants of concern. These products can be used on any real-time PCR machine using familiar protocols, whilst resulting in exceptional genotyping data.

Positive control templates for wild-type and variants are supplied in every kit to make data interpretation simple.

Our SNPsig® technology provides an alternative to sequencing as well as S gene target failure (SGTF) that enables scientists to analyse and monitor these specific genomic mutations.  Our kits can provide a pivotal role in screening for SARS-CoV-2 variants for the purpose of genomic surveillance and studies.

For the detection of the SARS-CoV-2 variants with the VUI-21APR-01 and VUI-21APR-03 (India)
Rapid detection of specific detection profiles
High priming efficiency
Sensitive to < 100 copies of target Positive copy number standard curve for quantification Accurate controls to confirm findings 96 reactions, includes master mix

Description

The ExcelTaq™ 5X PCR Master Dye Mix is a ready-to-use mixture for amplifying targeted DNA fragments. It is designed to serve as ready-to-use master mix for virtually all PCR applications. The mixture contains all components for PCR with the exception of template and primers. This not only saves valuable time in the laboratory, but also reduces the number of pipetting and reagent handling errors. The PCR Master Dye Mix is supplied as a 5X concentrated ready-to-use mix, that is a mixture of recombinant Taq DNA polymerase, reaction buffer, MgCl₂, dNTP, enzyme stabilizer and PCR-friendly loading dye solution containing tracking dye (Bromophenol blue) enabling efficient amplification of template in PCR and allows the user to prepare a PCR reagent – loading dye master mix conveniently.

Features

• 5’→3’ DNA polymerase activity
• No detectable 3’→5′ exonuclease (proofreading) activity
• Generates PCR products with 3′-dA overhangs
• High yield PCR 
• High reproducibility
• Reduced  pipetting errors
• Includes tracking dye for direct loading after PCR

Applications 

• Routine PCR
• Colony PCR
• High throughput PCR
• Amplification of DNA fragments up to 8 kb
• Generation of PCR products for TA cloning
• DNA labeling

Storage

4°C for 6 months
-20°C for 24 months
