Description

A segment of the edge of the axoneme showing the outer axonemal dynein arms that extend from the A-subfiber of a doublet to bind to the B subfiber of the adjacent doublet. TEM taken on 4/21/88 by C. Schroeder with Zeiss 10A operating at 80kV. Neg. 31,500X. Bar = 0.1µm. A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. A high resolution image (CIL:12036) is available for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
