    formic acid is also a rapid fixitive and decalcifier. We use it to treat bones to make them softer for histology so we can slice them into 4um cross sections (thats how microscope slides are made, then we stain them with pretty colours)

        In general Its nearly impossible to do vegan microbiology, everything contains animal products. mouse/goat/rabbit antibodies, bacterial culture plates require nutrients and they’re usually sheep or horse blood-based. Even cell cultures are technically live organisms, but so are plants I suppose.
