Laboratory studies of ReGenPRP

Separation and enrichment of thrombocytes with the ReGenPRP-Kit

Fig. 1 The ReGenPRP prepared according to the standard protocol (see page 16) shows a significant increase in the concentration of thrombocytes

Separation and enrichment in leukocytes, separation and reduction of the number of erythrocytes with the ReGenPRP-Kit

Fig. 2 : The ReGenPRP prepared according to the standard protocol (see page 16) shows an important increase in the number of leuko-cytes (in blue) and a significant reduction in the number of erythrocytes (in red).

Stability of growth factors and specific plasma proteins retrieved into the ReGenPRP
The preparation of the ReGenPRP (platelet-rich plasma) with the ReGenPRP-Kit is simple and rapid. Often, for organisational or technical reasons, it is necessary to prepare the quantity of the PRP required for the patient’s therapy the day before the operation. This is possible, because the growth factors and the plasma proteins, retrieved into the ReGenPRP, retain their biological activities for at least 20 hours, as long as PRP tubes are conserved at 4°C. Before used, the PRP and the activator are simply warmed for 10 minutes at 37°C. The results of stability tests are shown in figures 11 to 15.

Laboratory-medical evaluation of PRP prepared with the ReGenPRP-Kit

• Effective separation and enrichment of the cells necessary for healing (thrombocytes and leukocytes),
• The stability of the growth factors for at least 20 hours is observed when PRP is stored at 4°C,
• The efficacy of coagulation factors is preserved.
