  • Can you use PicoGreen in a Qubit assay?

    Hi,

    I purchased a picogreen kit to use on our fluorometer- turns out its actually broken.

    I've found a Qubit in the department, but Invitrogen have done the classic name change to turn all the specific reagents into undecipherable substance "x".

    Does anyone know if the buffer is simply 20x TE and the dye, picogreen?

    I'm trying to measure ds DNA and have already phoned their tech support to no avail. If anyone has a protocol or suggestions before I just go ahead and try it, that would be lovely!

    Many thanks,

    Craig

    Picogreen gave extremely similar results to the HS dye (+ HS buffer), but not the BR dye (+BR buffer). Picogreen also gave similar results to the HS dye when it was in buffer 1xTE diluted by 1:200 and 1:400.

      I am in a similar situation. Did you ever determine if the reagent is the same in both kits (i.e. is HS dye + HS buffer the same as the picogreen reagent)? Someone told me the concentrations may be different, which may affect the fluorescence/signal but I haven't confirmed that.

        The Impact of AI in Genomic Medicine
        by seqadmin



        Artificial intelligence (AI) has evolved from a futuristic vision to a mainstream technology, highlighted by the introduction of tools like OpenAI's ChatGPT and Google's Gemini. In recent years, AI has become increasingly integrated into the field of genomics. This integration has enabled new scientific discoveries while simultaneously raising important ethical questions1. Interviews with two researchers at the center of this intersection provide insightful perspectives into...

        Multiomics Techniques Advancing Disease Research
        by seqadmin


        New and advanced multiomics tools and technologies have opened new avenues of research and markedly enhanced various disciplines such as disease research and precision medicine1. The practice of merging diverse data from various ‘omes increasingly provides a more holistic understanding of biological systems. As Maddison Masaeli, Co-Founder and CEO at Deepcell, aptly noted, “You can't explain biology in its complex form with one modality.”
