HelpTest Code FHTGF Human Transforming Growth Factor beta 1 (TGF-b1)
Specimen Required
Specimen Type: Platelet-free Plasma
Container/Tube: Lavender top (EDTA)
Specimen Volume: 1 mL
Collection Instructions:
1. Draw blood in a lavender top (EDTA) tube.
2. Centrifuge for 15 minutes at 1000 x g within 30 minutes of collection. Centrifuge plasma again at 3000 x g for 10 minutes for complete platelet removal.
3. Aliquot plasma into a plastic vial and freeze at -20° C or below.
4. Send 1 mL platelet-free plasma frozen in plastic vial.
Additional Information:
For fixed speed centrifuges such as 645e: Within 30 minutes of collection, centrifuge 3 times for 10 minutes at 1600 x g while decanting the plasma each time before the next centrifugation. Aliquot plasma into a plastic vial and freeze at -20° C or below.

Clinical Information
Transforming growth factor (TGF) play a crucial role in tissue regeneration, cell differentiation, embryonic development, and regulation of the immune system. Transforming growth factor beta is found in hematopoietic (blood-forming) tissue and initiates a signaling pathway that suppresses the early development of cancer cells. It enhances the deposition of extracellular matrix and may play potential role in wound healing and cirrhosis formation. Many cells synthesize TGF-b and almost all of them have specific receptors for this peptide.
