Human Platelet Lysate (hPL) is a human-derived cell culture solution manufactured from platelets (thrombocytes). As a forward-looking cell culture supplement, human Platelet Lysate supports in vitro cell expansion. Compared with other cell culture supplements, our xeno-free product platform unites efficiency and safety like no other solution. The human Platelet Lysate platform named ELAREM™ covers all cell expansion needs. Imagine one technology supporting academic research as well as cell therapy – that is what ELAREM™ stands for. The combination of tailored solutions for different application fields enables an easy transition from bench to bedside.
Sustainability is the keynote of our ELAREM™ technology: The human platelets we reprocess to manufacture our products are recovered from blood donations. Platelets are obtained from healthy donors at licensed blood centres and admitted for transfusion. Due to patient safety reasons, platelets are not allowed for transfusion longer than 4 days. Instead of being disposed, we process unexploited platelet units. That is the starting point of a recycling process ending up in our ELAREM™ product platform.
Replacing animal sera, e.g. FBS (Fetal Bovine Serum), by human Platelet Lysate allows for cell expansion as well as clinical cell manufacturing. The elimination of xenogeneic risks and potential bovine prion transmission significantly extends the application possibilities. Our human Platelet Lysates are standardized and safe cell culture supplements ensuring high cell performance rates and reproducible results.
With our ELAREM™ platform technology, we follow the mission to support bench experiments as well as clinical applications. All with one solution and without animal suffering.
Furthermore, human Platelet Lysate contains abundant platelet-derived growth factors and cytokines, which stimulate cellular proliferation and maintain differentiation potential. Changing from FBS to human Platelet Lysate has the advantage that most cells proliferate faster, resulting in a greater number of cells in a shorter time. Moreover, tedious batch testing is eliminated. Large batch sizes ensure consistent products and, as a result, reproducible cell culture conditions. So there is no need to stock up the freezer in advance. Working with human Platelet Lysate saves you time and money.
Discover our FBS alternative ELAREM™ Prime that perfectly suits the needs of FBS users.
There are no restrictions if you switch from FBS (Fetal Bovine Serum) to human Platelet Lysate. You can change directly to human Platelet Lysate, without the need of a sequential adaption of the cells to the new supplement. The high amount of growth factors and bioactive molecules in human Platelet Lysate enables a direct replacement.
Our brand-new FBS alternative ELAREM™ Prime perfectly suits the needs of FBS users. ELAREM™ Prime is the world’s first human Platelet Lysate directly comparable with FBS – in terms of price and cell performance. This enables the simplest switch ever from animal serum to animal-free media. (Usually, human Platelet Lysate enhances cell proliferation significantly compared with FBS.)
The only thing that could occur whilst the first 2 passages, is a slight downturn in cell number (depending on cell type). Some cells briefly need to adapt to the changed supplement. After maximum 2 passages, you will be rewarded with fast cell proliferation.
Due to the high amount of growth factors and cytokines, our human Platelet Lysates are predestined to expand numerous human and animal primary cells and immortalised cell lines.
Since we take our customers’ feedback seriously, we have created an anonymous cell database. In this database, we collect the knowledge about the performance of our products on various cell types. If you have a question regarding a specific cell type or cell line, please let us know. We will then share (anonymous) information.
We recommend a concentration of 10% (vol./vol.) human Platelet Lysate in the cell culture medium. Our experience has shown that this concentration generally achieves best results. However, the final concentration of human Platelet Lysate in the cell culture medium can vary depending on cell type and experimental conditions. We recommend to determine the optimal concentration for the cells of interest. Some of our customers even use less than 5% (vol./vol.) human Platelet Lysate and are very satisfied with the cell performance.
Our products are manufactured from human platelets. Those raw platelets contain coagulation factors, including fibrinogen, to react to a bleeding by initiating a blood clot. We differentiate between fibrinogen-containing and fibrinogen-depleted human Platelet Lysates:
We also offer fibrinogen-depleted human Platelet Lysates: ELAREM™ Perform-FD and virus-inactivated ELAREM™ Ultimate-FDi. It is not required to add an anticoagulant if using one of these human Platelet Lysates.
After thawing the human Platelet Lysates, you may observe insoluble particles in the products. Don’t worry! Particulate formation does not affect cell culture performance. We have measured the function and can assure that there is no effect on the results.
If insoluble particles are disturbing, we recommend to remove particles by centrifugation of the pure human Platelet Lysate.
Our ELAREM™ product platform is 100% xeno-free. That goes along with our mission to offer animal suffering-free cell culture media. We think there is no need to use animal-derived cell culture media. Therefore, we also banished animal-derived anticoagulants from our portfolio. Instead, you will find a xeno-free synthetic anticoagulant, named ELAREM™ Supplement, in our online shop.
ELAREM™ Matrix Kit is our innovative and patent-protected two-phase cell culture system based on human Platelet Lysate. ELAREM™ Matrix Kit provides an animal component-free cell culture scaffold for 2D and 3D applications. The kit consists of ELAREM™ Matrix, a unique human Platelet Lysate gel, and ELAREM™ Accelerator, a xeno-free additive inducing instant scaffold gelation. This combination enables the three-dimensional embedding of cells within the gel scaffold as well as the two-dimensional cell seeding on a viscous surface. Cells can grow in several layers at the interface layer, which minimises contact inhibition with any artificial biomaterials.
Discover our ELAREM™ Matrix Kit.
ELAREM™ Matrix Kit covers numerous 2D and 3D cell culture applications. The patent-protected technology is both a nutrient source and a viscous scaffold in one – resembling the natural cell environment. That enables the three-dimensional embedding of cells within the gel scaffold as well as the two-dimensional cell seeding on a viscous surface. 3D bio-printing and coating cover some of the potential use cases.
Not yet. Our cell culture matrix is applicable for non-GMP cell expansion purposes. However, we are currently working on a GMP Grade version of ELAREM™ Matrix Kit to provide you a cell culture matrix for pre-clinical research and clinical applications.
Our products are stable until the expiry date stated on the product label.
All liquid human Platelet Lysates need to be stored frozen at -20°C until used.
