Frozen sectioning is preferred when paraffin processing would blunt antigenicity, enzyme activity, or certain molecular targets. Capital Biosciences embeds tissue in OCT, cuts on a cryostat, and can add staining when your study needs it.

• OCT embedding for stable orientation and cutting
• Cryostat sectioning to thin, even slices
• Optional routine or immunostaining on frozen sections
• Useful for IHC, enzyme work, and molecular applications that suffer under paraffin

Indicate whether you need unstained frozen slides, H&E, or sections reserved for antibody or nucleic-acid protocols.
