BioActive™ Secretory Protein Production

Seattle Genova's BioActiveTM platform is the world's best facility for biomedical research. We are dedicated to understanding how and why genetics, a discipline that is quickly developing, is altering the way we think about human health and paving the way for developments that will benefit all of humanity. Our extensive experience in producing secretory proteins safely for various biological study kinds. We are providing partners with complete tools so they may find, develop, and commercialize immunotherapy from concept to market, all for the benefit of customers around the world.

Any protein that a cell secretes, whether it is endocrine or exocrine, is referred to as a secretory protein. Numerous hormones, enzymes, poisons, and antimicrobial peptides are secretory proteins. The endoplasmic reticulum produces secretory proteins.

Proteins that are actively carried out of the cell are referred to as secreted proteins, which collectively make up the secretome. Although some human cells, such as B-lymphocytes and endocrine cells are specifically designed to produce proteins, all cells do so to some degree. Proteins which are released from the cell are important for both intracellular and intercellular interaction, as well as for numerous physiological, reproductive, and pathological activities.

Production of secretory protein

A secretory protein is created in the same way as other proteins. In the cytosol, where it interacts with a free cytosolic ribosome, the mRNA is generated and delivered. The N-terminal, the portion which is made initially, has a signal sequence of 6 to 12 amino acid residues containing hydrophobic side chains.

 SRP (Signal Recognizing Particle), a cytosolic protein, recognizes this sequence and helps transport the mRNA-ribosome complex to an SRP receptor in the endoplasmic reticulum membrane. by stopping translation.

Once the signal sequence reaches the ER, it is passed on to the reaction catalyzed, a protein-conducting channel in the membrane that enables the translocation of the freshly produced polypeptide to the ER lumen. The secreted protein's translation is restarted after SRP is released from the ribosome. The translocon is crossed by the generated chain as the intercalated is eliminated and translation proceeds (cotranslational translocation).


The secretory pathway is the most popular route used to move proteins outside of the cell. From the endoplasmic reticulum (ER), newly synthesized proteins are transported, passing via the Golgi apparatus, and then packed into vesicles.

The proteins are subsequently released into the extracellular space as a result of membrane fusion at the plasma membrane, where the vesicles are next transported (exocytosis). The signal peptide (SP), which consists of a short hydrophobic N-terminal region, is the sequence that targets proteins intended for secretion to the ER.

However, SPs can also be discovered in proteins that are intended for the ER, the Golgi apparatus, various types of vesicles, and the plasma membrane, which are divisions in the secretory pathway. 

The scaffolding proteins which make up a signal identification particle (SRP) that recognizes the SP direct the synthesized proteins to the rough ER.

With the aid of a protein complex known as the translocon, co-translational translocation of the newly synthesized peptide occurs at the ER membrane, resulting in the release of the newly generated protein into the ER lumen.

Via vesicles, proteins that pass quality control in the ER lumen are transported to the Golgi apparatus, where they undergo additional modification and sorting before being transported to their final destination, which is typically the plasma membrane, lysosomes, or secretion to the extracellular space.


A significant portion of blood diagnostic tests used in the clinic is focused on secreted proteins, highlighting the relevance of this class of proteins for medicine and biology in addition to being a rich source of new treatments and pharmacological targets. The cytokines, coagulation factors, growth factors, and other signaling molecules that are secreted have significant medical importance.


The purified proteins are also shipped to our customers for them to test internally.

The customer is sent all the protein purified in some phases.
