@proimmune.bsky.social has introduced Mastering Immunity 2026 – Shanghai, its symposium providing guidance to help drug developers manage immunogenicity risk.

Speakers include leaders in biotherapeutics, complex peptide drug developers, and regulatory authorities: www.proimmune.com/mastering-im...

This #FluorescenceFriday we use our Ankyron CJ30442 (cyan) to identify the lymphatic marker LYVE1 in skin, showing the extensive lymphatic network through to the individual oak-leaf-shaped endothelial cell on the Mica #microscope @leicamicrosystems.bsky.social. Learn more at proimmune.com/ankyron.

This #FluorescenceFriday we are shining a light on lymphatics in skin using Ankyron® clone DE40213, which binds Podoplanin (cyan). Image captured with our @discoverecho.bsky.social #microscope. Learn more about our recombinant antibody-replacements at proimmune.com/ankyron

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.

This #FluorescenceFriday we’re exploring microtubules using Ankyron® clone AP40945, which binds TBCA (red), with DAPI-stained nuclei (blue). Shown in HeLa cells. Image captured with our lovely @discoverecho.bsky.social #microscope. Learn more: proimmune.com/ankyron

If #FlowcytometryFriday is more your thing, then Ankyron™ AC40302 works well in this application, shown in HeLa (red histogram, with negative control of secondary fluorophore only in grey).

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.

#MicroscopyMonday! IHC with an insulin-specific #animalfree Ankyron AB40258 (brown) clearly identifying β-cells in islets of Langerhans of human pancreas (nuclei in blue) using #Leica autostainer and @discoverecho.bsky.social #microscope in colour camera upright configuration. proimmune.com\ankyron

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

We were happy to see that this Ankyron also works well in #FlowCytometry, with HUVEC stained with V5-tagged Ankyron and anti-V5 APC (red). Negative control, anti-V5 APC only (grey).

Shining a light on Endoglin (aka CD105) for #FluorescenceFriday, shown in red using #animalfree Ankyron™ clone AY40419 (nuclei blue), highly expressed in vascular endothelial cells like these HUVEC with crucial roles in angiogenesis & TGFβ signaling. On our @discoverecho.bsky.social #microscope

This dendritic cell is ready for #FluorescenceFriday! Here, we used our interferon-α8-specific #animalfree Ankyron™ ANK01178_5_AW40550 (red) and nuclei counterstained with DAPI (blue) on @discoverecho.bsky.social #microscope

Our very own Emilee Knowlton, Ph.D., Senior Immunology Sales Specialist, will be speaking at this event about "An Integrated Approach to Managing Immunogenicity Risk and Optimum Protein Design".

We're sponsoring #festofbiologics where science meets strategy!

Join us on April 23-24 in San Diego. From cutting-edge research to advancements in AI-driven drug discovery, this is where breakthroughs happen.

And here's the same #animalfree Ankyron™ specific to β-actin (red), lighting up the cytoskeleton that we highlighted for #FluorescenceFriday last week:

Is #WesternBlotWednesday a thing?! Why not celebrate those perfect western blots? Here's our #animalfree Ankyron™ specifically binding human β-actin (37.3 kDa), both recombinant protein and in cell line lysates. Perfect loading control for westerns!
