Nový krvný test prináša bezkonkurenčnú citlivosť a špecificitu, čo umožňuje vývoj testov novej generácie. 

FREMONT, Kalifornia, 10. október 2025 /PRNewswire/ -- Spoločnosť Alamar Biosciences, ktorá využíva presnú proteomiku na včasnú detekciu ochorení, dnes oznámila uvedenie testu NULISAqpcr™ BD-pTau217 – transformačného pokroku v kvantifikácii fosforylovaného tau 217 (pTau217) odvodeného z mozgu na základe krvných testov – kľúčového biomarkera vo výskume Alzheimerovej choroby a iných tauopatií. Tento prvý test svojho druhu je jediným dostupným jednoplexným riešením odvodeným od mozgu, ktorý stanovuje nové kritérium pre presnosť a špecificitu pre CNS vo výskume neurodegeneratívnych ochorení.

Test NULISAqpcr BD-pTau217, postavený na patentovanej platforme NULISA™ od spoločnosti Alamar, poskytuje bezprecedentnú citlivosť a špecificitu z neinvazívnych typov vzoriek, ako sú plazma, sérum a vysušené kvapky krvi. Priame meranie pTau217 odvodeného z CNS v rámci výskumného testu bez potreby odberu mozgovomiechového moku (CSF) alebo PET zobrazovania odstraňuje existujúce bariéry širokého prijatia v populačných štúdiách alebo longitudinálnych klinických skúškach.

„Test NULISAqpcr BD-pTau217 prináša novú definíciu možnosti kvantifikácie biomarkerov CNS," uviedol Dr. Yuling Luo, zakladateľ, predseda predstavenstva a generálny riaditeľ spoločnosti Alamar Biosciences. „Odstránením šumu z periférnych zdrojov tau proteínu dokážu vedci teraz odhaliť zásadné zmeny v mozgu skôr a s vyššou presnosťou."

„Výkonnosť testov pTau217 pre plazmu špecifickú pre mozog od spoločnosti Alamar je vynikajúca," povedal Jonathan Schott, MD, PhD, profesor neurológie na University College London. „Naše rané výsledky naznačujú, že pri detekcii patológie Alzheimerovej choroby s kognitívnymi príznakmi jednoplexný formát funguje prinajmenšom rovnako dobre ako zaužívané testy plazmatického ptau217, ale má vyššiu zmenu násobku a vedie k menšiemu počtu vzoriek klasifikovaných v neurčitom rozsahu. Mozgovo-špecifické pTau merané vo výskumnom prostredí pomocou multiplexného testu vykazujú veľký prísľub pri detekcii asymptomatických jedincov s vysokou úrovňou patológie Alzheimerovej choroby, ktorí môžu byť kandidátmi na klinické skúšky terapií účinných na ochorenie."

Test BD-pTau217, ktorý je k dispozícii ako jednoplexný test NULISAqpcr alebo v rámci multiplexného panelu NULISAseq™ CNS Disease Panel 120, podporí objavný aj translačný výskum. Automatizovaný pracovný postup testu umožňuje spracovanie viac ako 220 vzoriek denne pomocou systému ARGO™ HT, vďaka čomu je ideálny pre vysokovýkonnú analýzu v skupinách ochorení alebo populačných štúdiách. 

Spoločnosť Alamar Biosciences naďalej spolupracuje s neurovedeckou komunitou s cieľom odhaliť poznatky o biomarkeroch, ktoré urýchľujú pokrok v liečbe Alzheimerovej choroby a ďalších oblastiach. Viac informácií nájdete na stránke alamarbio.com.

Testy NULISA BD-pTau217 sú určené len na výskumné účely a nie na použitie v diagnostických postupoch.

O spoločnosti Alamar Biosciences, Inc.
Alamar Biosciences je súkromná spoločnosť v oblasti biologických vied, ktorej poslaním je podporovať presnú proteomiku, s cieľom odhaľovať choroby čo najskôr. Patentovaná platforma NULISA™ spolu so systémom ARGO™ HT plynulo spolupracuje s najnovšími pokrokmi v genomike a dosahuje jednocifernú citlivosti attomolárnej detekcie, čím výrazne prevyšuje najcitlivejšiu technológiu detekcie proteínov na súčasnom trhu.
