This service provides expert embedding of fresh or fixed tissue samples in Optimal Cutting Temperature (OCT) compound. OCT embedding is a critical step for preparing frozen tissues for cryosectioning while preserving tissue morphology and antigenicity for applications like immunohistochemistry, immunofluorescence, and molecular studies., The service ensures proper orientation and freezing of samples, resulting in high-quality blocks suitable for cutting thin, intact sections on a cryostat.
