Can I use other dyes besides the Green Fluorescent Dye available in the LavaLAMP™ DNA Component Kit with Dye?

Yes. Syto-13 (Molecular Probes) and EvaGreen (Biotium) have both been tested with the LavaLAMP DNA Master Mix and they perform well.

What if I don’t have a fluorimeter? How else can I monitor the reaction?

Amplified products can also be monitored by viewing the reaction on an agarose gel or by measuring the turbidity of the reaction at OD600.

Which instruments can be used to monitor the real-time fluorescent assays?

See the User Manual for a list of instruments that have been tested at Biosearch Technologies. Basically, any instrument capable of maintaining stable reaction temperatures and detecting fluorescence in the FAM (fluorescein) channel will work.

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.

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.

Are there specific recommendations for performing 1-step RT-qPCR on RNA isolated from clinical samples?

PCRAMP-021

The nucleic acid (either DNA or RNA) will most likely need to be purified from clinical samples due to sample/transport media specific inhibitors and RNAses. For example, for RNA purification, we recommend our sbeadex‚Ñ¢ Pathogen Nucleic Acid Purification Kit for optimal purification.

Why are genotype calls not achieved for specific targets?

AMPSEQ-001
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.

How do you determine the brightness of a dye?

The absolute intensity of a dye is a product of the extinction coefficient and the quantum yield. We have not measured the quantum yield for our dyes as this value is highly dependent upon the local environment, including the buffer system used for the measurement. However, we do provide the extinction coefficients for dye modifications at their lambda max wavelength, and these values are available under the Technical Specs tabs of our Oligo Modifications webpages. While quantum yield and extinction coefficients both contribute to dye detectability, the principal determinant for Stellaris® RNA FISH assays is actually the instrument optics, including the excitation source, available filters, and quantum efficiency of the camera.
