A technique for processing mucous coated marine invertebrate spermatozoa for scanning electron microscopy.
A technique for preparing heavily mucous coated marine invertebrate spermatozoa for scanning electron microscopy (SEM) is described. This technique involves washing in 1500 NF units/ml hyaluronidase in millipored sea water to remove mucus, followed by fixation in glutaraldehyde and osmium tetroxide. Following primary fixation, spermatozoa are enclosed in Nuclepore membrane bags positioned within Teflon specimen capsules allowing them to be processed and critical point dried without excessive mechanical damage or loss.
