We have posted our second Hong Kong paper on bioRxiv! We developed species-specific qPCR primers and a TaqMan probe for detecting Chinese white dolphins. The specificity and sensitivity were meticulously tested.

Our first Hong Kong paper was published in Environmental DNA! onlinelibrary.wiley.com/doi/10.1002/...

We developed cetacean-specific eDNA primers, named µCeta. Please try it if you are interested in cetacean eDNA metabarcoding!
μCeta: A Set of Cetacean‐Specific Primers for Environmental DNA Metabarcoding With Minimal Amplification of Non‐Target Vertebrates
Cetacean eDNA metabarcoding results from the aquarium pool samples using new cetacean-specific primers. μCeta shows superior performance to detect and differentiate different cetacean species.

🙏 And just as an addition: don‘t use these primers for bulk sample metabarcoding. There others are ways better (we recommend fwhF2/fwhR2n as a good solution; further solutions like BF2/BR3 or mlCOI with dgHCO exist)

Our new preprint published! (My first Hong Kong paper!)

We developed a new eDNA primer set, named µCeta, to detect cetaceans. It can avoid amplification of non-target eDNA such as human and fishes, enabling more sensitive and efficient detection of cetacean eDNA. www.biorxiv.org/content/10.1...

This is a ‘lickometer’.

Researchers have used it to understand how the rodent brain might be coding kinematic, reward, and difficulty parameters, particularly while moving around.
