Are Endura High-Yield Electrocompetent Cells classified as genetically modified organisms (GMO)?

COMCEL-017
Depending on the definition of GMO, yes, they are GMO as they were constructed by methods outside of E. coli conjugations or viral transductions. However, they do not contain DNA from organisms other than E. coli.

Can intercalating dyes be used with this mix?

BHQ-001

BHQ Probe Master Mix has been optimised for use with hydrolysis-probe based chemistry, for both end-point genotyping and qPCR applications. For use with intercalating dyes, we would recommend that you perform your own optimisation and validation to ensure reproducible sensitivity and specificity is achieved using your selected dye.

Do you have any recommendations for purifying DNA from difficult biological samples such as plant leaves and seeds before shearing?

NXGSEQ-003, NXGSEQ-004, 15300-1, NXGSEQ-001, NXGSEQ-002

No. We do not have any specific recommendations for DNA purification. However, the purified DNA should be high quality with A260/280 ratios above 1.8. The DNA should also be free of detectable RNA contamination. Prior to shearing/fragmentation, the purified DNA samples can be analysed on 0.7% agarose gel to check for sample degradation and RNA contamination.

Have you produced proteins at scale?

COMCEL-008

Our customers have reported growth of ClearColi strains in a 5 litre fermenter and shown optical density levels in excess of 150, and that some defoaming agents (particularly silicone-based defoamers) are beneficial while other defoaming agents such as polypropylene glycol may inhibit cell growth.

Should I use electrocompetent or chemically competent cells to make my library?

We recommend using electrocompetent cells for library generation, because the transformation efficiency for electrocompetent cells is higher. Higher transformation efficiency preserves library diversity.

Can Amp-Seq technology be used in human clinical diagnostics?

AMPSEQ-001
Currently, we are unable to support human clinical diagnostic applications.

Does Amp-Seq provide data analysis software to generate genotype calls?

AMPSEQ-001
Biosearch Technologies provides an analysis pipeline (the BiosearchCaller software), compatible with the Amp-Seq technology, to produce genotypes from the sequencing data. The software can be accessed via a cloud system and our technical team will support the deployment and initial setup.

Can Amp-Seq One technology be used in human clinical diagnostics?

AMPSEQKIT1
Currently, we are unable to support human clinical diagnostic applications.

Does Amp-Seq One provide data analysis software to generate genotype calls? 

AMPSEQKIT1
Biosearch Technologies provides an analysis pipeline (the BiosearchCaller software), compatible with the Amp-Seq One technology, to produce genotypes from the sequencing data. The software can be accessed via a cloud system and our technical team will support the deployment and initial setup.

Why are genotype calls not achieved for specific targets?

AMPSEQKIT1

Sometimes, despite a successful primer design for a target, genotyping calls are not achieved for a specific target. This can be caused by several issues including poor primer design and issues with the synthesis of the primers. In addition, if genomic reference data for both parental strains is not provided for target primer design, some primer pairs might not work for all F1 samples.

Missing genotypes are generally attributed to low depth. Certain targets cannot be amplified because of sample quality issues or unknown parental bias in the genomes. Our standard design process addresses the parental bias by avoiding primers on known variability in the genome. Known variation information can be provided to us in the target flanking sequences through the Data Submission form.
