This #FluorescenceFriday we used our recombinant target binding reagent Ankyron® clone CE30111 (green) to detect Perlecan in the extracellular matrix deposited by HUVECs, with nuclei counterstained using DAPI (blue). Image captured using our brilliant @discoverecho.bsky.social #microscope.

I am thinking the left image is AI… it is too perfect. Which is the correct though?

Fascinating insights this #FluorescenceFriday, into complement delay-accelerating factor (DAF, CD55), identified by our Ankyron™ AC40301 (red) in HeLa cells (nuclei, blue) on @discoverecho.bsky.social #microscope.

This #FluorescenceFriday we use an Ankyron™ to specifically label the Golgi apparatus marker RCAS1 (red), counterstaining actin cytoskeleton (green) and nucleus (blue) on @discoverecho.bsky.social microscope. Look out for our other organelle-specific #animalfree Ankyrons™ at proimmune.com\ankyron
I disturbed another occupant of the Oxford Science Park but they were illegally fishing - goldfish saved!

Delighted that we contributed to exciting work from Zuben Sauna’s lab (FDA) using Ankyrons™ specific to 3 #COVID19 spike protein variants, which neutralized all 3 in a pseudovirus-based neutralization assay.

I love being part of this project and product line. Also, continually impressed at the sharpness of the images we achieve on our (epifluorescence) Echo Revolve microscope through the digital haze reduction software

For #WindowsWednesday a view of Stourhead #nationaltrust from a room not usually open to the public. The guides were amazing and really brought it to life
Ooo I do like the thought about the hair - let’s hope they lived happily ever after and exchanged hair products for all their days ❤️
Am I just being a cynic but isn’t she looking into the jewels on his crown rather than into his eyes?!
