U937 Delta ST on VCAM-1 and Poly-L-lysine, activated (N-fMLFF)

Sample 1: Coverslips base-treated, coated with Recombinant Human VCAM-1/CD106 Fc Chimera (R&D Systems #P19320) for 30 minutes at room temperature, and gently washed 2 times with Hepes buffer. Treated with 0.5g% BSA for 30 minutes. Cells resuspended in Hepes on the coverslips for 30 minutes at room temperature, then washed with Hepes to remove unattached cells. Finally, treated with N-fMLFF Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://api.formulasearchengine.com/v1/":): {\displaystyle 10^{-7}} PBS buffer.

Cells are attached, but remain globular with no protrusions.
