We were wondering how to store the dissolved transferrin. We have frozen it at -80. If we thaw it can we can freeze it again,
1 answer-
Transferrin is fairly stable in solution. Non-sterile aqueous solutions may be stored at 4 °C for 5-10 days. Solutions may be filter-sterilized to extend solution stability. Various media supplements containing transferrin, such as ITS (Insulin/Transferrin/Selenium), are stable for up to 30 days at 4 °C and may be stored in frozen aliquots at -20 °C. for up to one year. Avoid repeated freeze/thaw cycles as this may contribute to precipitation occurring.

What is the carbohydrate content of human transferrin?
1 answer-
We have found the information on transferrin in a reference book:The Plasma Proteins, F.W. Putnam, ed, volume 2, chapter 4, Table II.According to the table, Transferrin is 6 percent carbohydrate, citing G.A. Jamieson, J. Biol. Chem. 240(7), 2914-2920 (1965).The table also gives information on the percentage of each type of monosaccharide that is present.
