Segmentation by type focuses on the physical and processing attributes of defibrinated sheep blood, which influence handling, shelf‑life, and regulatory compliance. The market is split among liquid, frozen, and lyophilized formats. Liquid blood, typically supplied in sterile bottles, commands a premium due to its immediate usability but requires cold‑chain logistics, representing roughly 40 % of sales. Frozen blood, stored at –20 °C, offers extended stability and is preferred for large‑scale research batches, contributing about 35 % of the market. Lyophilized (freeze‑dried) blood, reconstituted on‑site, provides the longest shelf‑life and eliminates cold‑storage costs, capturing the remaining 25 %. Within each format, sub‑variants such as gamma‑irradiated, preservative‑added, or filtered products address specific biosafety or purity requirements, further refining the market taxonomy.
