InVitria at the American Association of Immunologists 2018 Conference

Posted By Randy Alfano Ph.D. on 5/18/18 9:59 AM


This year at the American Association of Immunologists 2018 Conference in Austin, Texas, I had the pleasure of meeting some of the field’s brightest scientists deep in my home town. While enjoying only a small sample of blues, rock, country music and some Texas-authentic Tex-Mex that the live music capital of the world has to offer, I was able to catch up on some of the latest developments in the field, network with colleagues, and speak with scientists presenting their latest research.

Transferrin: An Iron Transport Protein - Recombinant Human Transferrin in Cell Culture Media

Posted By Randy Alfano Ph.D. on 5/16/18 11:17 AM

Transferrin is an iron binding protein found in blood plasma that is critical to cell health. Transferrin supplies iron to cells naturally in the body and as a supplement in cell culture media.


Transferrin Function and Structure

Human serum transferrin, a bilobal ~75 kD glycoprotein that has the ability to reversibly bind Fe3+ with nanomolar affinity, represents one of the major vehicles for iron delivery to cells both in vivo and in vitro3. Produced in the liver, transferrin is found in the blood plasma as a heterogeneous population at approximately 2.5 mg/mL consisting of diferric (holo or iron-saturated), monoferric N-lobe, monoferric C-lobe (partially iron saturated) or apo transferrin4.
