The Extract-N-Amp™ kits are designed to rapidly extract and amplify genomic DNA. The plant tissue version of these kits has been optimized to amplify without concern over plant inhibitors. This technical document will discuss the versions of this kit that
The entire PCR workflow is vulnerable to factors which introduce variability. Many of the variable components are unavoidable, such as the source of the sample or the requirement for a reverse transcription step. Assay design is also highly variable and
Standard methods for extracting DNA from tissues can be extremely laborious and time consuming. Certain applications, such as genotyping of transgenic mice using a section of tail, employ a lengthy DNA extraction process.
Preserved samples from medical, forensic, museum and other archival collections represent a rich source of study material, much of it meticulously collected, characterized and preserved through many decades of work by experts in the field
Whole genome amplification (WGA) offers a means to overcome the above restrictions for single-cell genomic analyses. WGA has been described as a non-specific amplification technique that affords an amplified product completely representative of the initial starting material.
Transplex Whole Transcriptome Amplification (WTA2) exponentially amplifies RNA producing a double-stranded cDNA library while precisely maintaining differential levels of individual transcripts in test and reference samples.
Developing a PCR or RT-PCR/RT-qPCR troubleshooting protocol so that data are reliable is essential. Potential sources of RT-PCR or PCR error and problems include operator error, the PCR master mix, and oligo design. This PCR troubleshooting guide outlines and details
When developing a PCR troubleshooting protocol, it is important to be open to any possible sources of error, however insignificant they may seem, in order to explore each potential problem independently.
While many PCR assays are developed for research applications there are further considerations for those that are being developed to become diagnostic assays or to be performed in support of: Biologics License Application (BLA), New Drug Application (NDA), Premarket Approval
In recent years, array-based Comparative Genomic Hybridization (aCGH) has been refined to determine chromosomal changes at progressively higher resolutions. This evolving technology is, however, somewhat hampered by the large DNA input requirement—a minimum of 150,000 copies of a human genome
Efficient qPCR relies on good assay design. Since the invention of PCR, many parameters have been identified as important for assay quality, such as estimates of oligo temperature characteristics, GC content and folding properties.
