The rising popularity of platelet-rich plasma treatments has given birth to several competing PRP kits. The efficacy of PRP treatments depends on delivering a therapeutic dose of viable platelets directly to damaged tissues, and platelet recovery rates vary substantially between commercially available kits, according to third-party research. This article discusses the primary differences between the Stryker Regenkit and EmCyte Pure PRP kits, including centrifugation protocols and platelet recovery rates.
Physicians seeking to improve patient outcomes with PRP treatments would be interested to learn that EmCyte Pure PRP kits have been shown to produce PRP with platelet concentrations 7x higher than whole blood while Regnekit was shown to produce PRP with 30% fewer platelets than whole blood.
These substantial differences are rooted in divergent approaches to centrifugation. Regent relies on the simplicity of single spin preparation while EmCyte PRP further concentrates platelets with a dual-spin approach.

Both kits rely on the principles of differential centrifugation to isolate platelets. While under the radial force of centrifugation, the various components of whole blood are separated by weight. The heaviest elements, red blood cells, travel at a faster rate and settle at the bottom of the kit followed by white blood cells, platelets followed by plasma at the top.
Emcyte Pure PRP kit protocols call for the initial supernatant to undergo secondary centrifugation. During this subsequent centrifugation blood elements become more clearly stratified and additional platelets fall out of the plasma solution. The secondary centrifugation yields PRP serums with higher platelet recovery rates.
