For biomedical research, a broad array of proteins and peptides are preferred choices. However, during the storage of biospecimens and coagulated blood, many useful proteins are lost, hampering research efforts. This is where ProteinSafe plays a crucial role. Any biological sample, including blood, can be directly transferred to the ProteinSafe reagent and stored for an extended period without the loss or denaturation of proteins. ProteinSafe ensures the integrity of proteins in all research samples. Typically, biorepositories store samples in different aliquots to ensure the safety of multiple processing methods. However, ProteinSafe simplifies this procedure by enabling one-term collection and storage for a longer period, ensuring the stability of existing proteins in the collected samples.
