A high resolution of some tubules near a contractile vacuole that appear to be decorated with pegs similar to the spongiome of the CV of Paramecium. In Paramecium these pegs are known to be V-type proton pumps (V-ATPases). Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. TEM taken on 3/2/69 by R. Allen with Philips 300. Neg. 12,500X. The raw film was scanned with an Epson Perfection V750 Pro. This high resolution image is available for quantitative analysis. Additional information is available at (http://www5.pbrc.hawaii.edu/allen/).
