methods for tissue separation / extraction

[vet451]

Hello,

 

I'd like to extract an arthropod from a biopsy of animal skin for identification. The mite is small, about 100um, and embedded in a column of tissue. It's too small to manually cut out under magnification using available tools. It's currently preserved in 70% ethanol.

Ideally I would isolate it by loosing or dissolving the surrounding tissue without destroying its features. I'd like to conduct a visual inspection prior to sequencing for species identification. Specific suggestions and techniques welcome. Thanks.
