Superior cell performance
Human Platelet Lysate (HPL) provides superior cell performance and cell expansion when compared to other supplements such as FBS or chemically defined media. PLTGold® HPL is a revolutionary xeno-free, heparin-free supplement which provides rapid cell expansion with proven success across various cell types including MSCs and immune cells. Available in research and clinical grades, PLTGold® is an excellent supplement to cell culture media and for use in both 2D and 3D culture systems with a focus on research and cell therapy applications.

How much human platelet lysate should I add to my media or cultures?
Cells grown in human platelet lysate typically use half the concentration compared to cells cultured in fetal bovine serum. Standard protocols suggest adding 5% concentration. However, we recommend titrating anywhere between 2-10% in order to maximize cell growth and narrow in on the best concentration for your cultures.
Is it possible to add too much HPL to my cultures?
Yes, with HPL it is possible to add too much to your cultures. We’ve seen that HPL can slow the growth of MSCs at high concentrations.
What is the difference between research-grade and clinical-grade human platelet lysate?
Both grades are manufactured under the same conditions and follow the same protocols. The clinical-grade product includes additional endotoxin testing and batch record documentation. All products have a CofA available.
What is PLTGold human platelet lysate?
PLTGold is a completely xeno-free human platelet lysate which contains all essential growth factors for healthy cell growth. Donor units are pooled in large batches and manufactured by Mill Creek Life Sciences under a proprietary method to produce highly consistent and reliable lots.
Can PLTGold be used in clinical trials?
Yes, PLTGold is a completely xeno-free supplement that does not require heparin (or used in the manufacturing process). PLTGold has an FDA registered drug master file available for reference.
What is the intended use for platelet lysate?
Large-scale expansion of cells including MSCs, T-cells, hematopoietic stem cells, iPSCs, tumor cells, and fibroblasts.
Superior xeno-free alternative to FBS and serum-free media solutions. Minimizes lot-to-lot variability.
