Dabei wird ein konzentrierter Pool thrombozyt\u00e4rer Wachstumsfaktoren (PDGF, TGF-\u03b2, EGF, VEGF, FGF-2, IGF-1) ins Plasma freigesetzt. hPL dient als xenofreie, GMP-kompatible Alternative zu FKS in der humanen Zellkultur \u2013 besonders in der MSC-Expansion.<\/p>\n<\/div>\n\n<h2>Wie wird hPL hergestellt?<\/h2>\n<p>Thrombozyten werden von gescreenten menschlichen Spendern per Apherese oder Vollblutspende gewonnen. Das Thrombozytenkonzentrat durchl\u00e4uft 3\u20135 Gefrier-Tau-Zyklen (typischerweise \u221280 \u00b0C \u2192 37 \u00b0C), die die Zellmembranen der Thrombozyten aufbrechen und den Zellinhalt freisetzen \u2013 dichte Granula (ADP, Serotonin, Calcium), \u03b1-Granula (PDGF, TGF-\u03b2, EGF, vWF, Fibronektin) und lysosomale Inhalte \u2013 ins umgebende Plasma. Anschlie\u00dfend wird das Lysat filtriert (0,2 \u00b5m) und aus mehreren Spendern gepoolt, um Chargenschwankungen zu verringern.<\/p>\n\n<!-- SB-BUY-BOX --><div style=\"border:1px solid #daf3f2;border-left:4px solid #18b7b2;background:#f1faf9;border-radius:0 10px 10px 0;padding:14px 18px;margin:18px 0 26px;font-size:15px;line-height:1.6\"><strong>Bereit zu bestellen?<\/strong> <a href=\"https:\/\/seamlessbio.de\/de\/humanes-thrombozytenlysat-hpl\/\" style=\"color:#18b7b2;font-weight:700\">Humanes Thrombozytenlysat (hPL) kaufen \u2192<\/a><br><span style=\"font-size:14px;color:#5b6b71\">Research-, GMP- und GMP-Clinical-Qualit\u00e4t \u00b7 fibrinogen-depletiert, heparinfrei \u00b7 kostenloses Testmuster<\/span><\/div>\n<h2>hPL vs. FKS \u2013 die wichtigsten Unterschiede<\/h2>\n<p>Anders als FKS liefert hPL Wachstumsfaktoren mit menschlicher Sequenz, die f\u00fcr humane Zellkulturen artgleich sind.
