In an attempt to find whether there are predictable peaks along the collagen like domain of SP-D arms two different types of AFM images (Arroyo et al mentioned amplitude modulation mode) I measured (in the supplemental figures 2 and 4). Plots using FIJI (Image2, ImageJ, all three versions seem to perform similarly) in these two comparisons show three distinct and one not so distinct peaks in the collagen like domain. Pink dotted rectangles show peak valleys that seem to correspond between the height image with hand drawn line (top part of the figure), and the flat image with LUT plots drawn from a node-cusp line drawn on the grayscale (converted from image in middle) (middle and bottom part of my composite figure). N termini (left brightest portion of the dodecamer, CRD on the right.

Science illustrations fun reminders: coronavirus charms, patterns for cross stitch, fridge magnets
Science illustrations fun reminders: coronavirus charms, patterns for cross stitch, fridge magnets — all made with some accuracy for the real SARS Cov 2 anatomy in mind. This has been an education for me, firstly in modeling proteins on RCSB and the pluses and lacks theirin, also for learning a little about virology, even more importantly, for releasing that pent up emotion over this crisis, having to work from home – which has its own problems and rewards and not knowing whether the crisis politically drive, fear driven, whether this approach is good for society and the economy or bad for society and the economy, which leaders are telling facts which are telling fiction, and knowing the final impact will only be known in the passage of time).
BUT – here are some fun (at least fun for me) products of these last two months (made without apology and without fear).
