Test ID 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: Draw blood in a lavender top (EDTA) tube(s).

Following centrifuge instructions below, spin down and send 1 mL platelet-free plasma frozen in plastic vial.

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. Freeze at -20° C or below.

For fixed speed centrifuges such as 645e: Collect in lavender top tube using EDTA as an anticoagulant. Centrifuge 3 times for 10 minutes at 1600 x g while decanting the plasma each time before the next spin within 30 minutes of collection. 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.
