biotin/streptavidin position on A tile of 2D DNA array (see next slide)staple:m13 5:1 • [m13]=10 nm • SA:biotin staple 15:1 • this annealing run was not dialyzed before adding SA and imaging
Two biotin on each side of A tile SA labeled A tile 58.88nm
below is a flowchart type key to the AFM images in the subsequent slides, any images that are not square can be assumed to have long side (X) length equal to the Y range seen on side of image. Unless otherwise stated, all images on a single .ppt slide are of the very SAME mica surface/depostion. Also, unless stated, deposition was by 5 min. incubation of origami soln. on mica followed by single HOH rinse. A subunit with total 4 biotin B subunit with no biotin A subunit with total 4 biotin B subunit with no biotin + + + 15:1 SA:biotin staples anneal over weekend anneal over weekend AB array X AFM #1 (mica) AB array YSA AB array X 66nM SA (15:1) + 66nM SA (15:1) + AB array YSA 4 deg C overnight 4 deg C overnight AFM #2 (mica) AB array XSA AB array YSASA All AFM images shown in final 6 slides of this presentation were previously shown in group meeting by Massud and are of AB array XSA
AFM #1 AB array YSA first mica after one HOH rinse
AFM #1 AB array YSA same mica after second HOH rinse
AFM #2 AB array YSASA first mica after one HOH rinse
AFM #2 AB array YSASA second mica one HOH rinse
AB array X AFM #1
AB array XSA AFM #2 this is the first piece of mica imaged, TAE rinsed at left, TAE rinse followed by HOH rinse below
AB array XSA AFM #2 second piece mica imaged- rinsed x2 with HOH, these images are all of one mica surface/one deposition; continued next slide
AB array XSA AFM #2 second peice mica imaged- rinsed x2 with HOH, these images are all of one mica surface/one deposition; the only difference between this slide and the 2 preceding slides is that the same mica surface seen in previous 2 slides, sat in covered dish in ambient conditions for 6 days prior to acquisition of the images on this slide
Massud included the following slides in his 6-21-11 presentation
SA labeled 2D cross DNA origami array (this and all slides following are of AB array XSA)
