- — 20 mM glycine,
- — 100 mM Trehalose,
- — 200 mM Mannitol,
- — 20 mM NaH2PO4 (pH 7.4);

Purity and identity was determined by Nanosight LM10 measurements. Protein was measured using Lowry standardized assay, DNA/RNA concentration was measured using standardized Qbit analysis assay. Sterility test of vialed product was performed according to Eur.Pharm. (Inoculation method). Endotoxin was determined using the gel clot assay according to Eur.Pharm.
Cargo & Protein Profile
ExoTec™ vesicles are highly characterized to ensure reliable expression patterns in research. Standard marker expression includes tetraspanins CD9, CD63, and CD81, which are verified via Western Blotting and flow cytometry. Additionally, internal markers TSG101 and ALIX confirm the endosomal biogenesis pathway typical of true exosomes.

Quality & Reconstitution
To preserve structural integrity and prevent cargo leakage, ExoTec™ is supplied as a lyophilized powder. Reconstitution is recommended with our sterile buffer (20 mM glycine, 100 mM Trehalose, 200 mM Mannitol, 20 mM NaH2PO4 at pH 7.4). The vialed material exhibits high sterility and ultra-low endotoxin levels (<2.3 EU/mg), suitable for downstream cell-culture assays.
