Glycoproteina spiculata in superficie novi coronaviri exstant et facile mutantur, ut Alpha (B.1.1.7), Beta (B.1.351), Delta (B.1.617.2), Gamma (P.1) et Omicron (B.1.1.529, BA.2, BA.4, BA.5).

Nucleocapsidum virale ex proteina nucleocapsidi (proteina N breviter) et RNA constat. Proteina N relative stabilis est, maxima proportio in proteinis structuralibus viralibus et alta sensibilitas in detectione.

Ob proprietates proteini N, anticorpus monoclonale proteini N contra novum coronavirus electum est in evolutione et consilio apparati nostri ad auto-probandum Antigenum, nomine "SARS-CoV-2 Antigen Rapid Test (Colloidal Gold)", quod ad detectionem qualitativam Antigeni SARS-CoV-2 in speciminibus penicilli nasalis in vitro per detectionem proteini N destinatur.

Id est, pro hodierna stirpe mutante glycoproteini spiculae, qualis est Alpha (B.1.1.7), Beta (B.1.351), Delta (B.1.617.2), Gamma (P.1) et Omicron (B.1.1.529, BA.2, BA.4, BA.5), effectus Probationis Rapidae Antigeni SARS-CoV-2 (Aurum Colloidale) a societate nostra producti non afficietur.
