Ngwa
Nnwale in vitro maka ikpebi ọnụọgụ HbA1c n'ọbara mmadụ niile na sistemu fotometric.HbA1c bụ ngwaahịa hemoglobin (Hb) nke na-emepụta mmeghachi omume glycation na-adịghị ngwa ngwa na nke na-aga n'ihu n'okpuru glucose ọbara dị elu.Glucose na-agbanwe hemoglobin kpọmkwem na n-terminal valine residue iji mepụta haemoglobin glycated.N'okpuru ọnọdụ physiological nkịtị, mmepụta nke ngwaahịa mmeghachi omume glycosylation na-abụghị enzymatic dabara adaba na ntinye nke reactants.Ebe ọ bụ na mkpokọta hemoglobin ka kwụsiri ike, ọkwa glycosylation na-adaberekarị na ntinye glucose yana metụtara ogologo haemoglobin na mkpughe glucose.Ya mere, HbA1c bụ ezigbo ihe na-egosi ọkwa glucose ọbara nke ndị ọrịa n'ime ọnwa 2-3 gara aga.
Ụkpụrụ
N'okpuru ọrụ nke protease, a na-ebipụ n-terminal nke yinye β na HbA1c ma hapụ glycosylated dipeptides.Na mmeghachi omume mbụ, enwere ike nweta ntinye uche Hb site na ịlele nnabata nke 480 nm.Na mmeghachi omume nke abụọ, fructosyl peptide oxidase (FPOX) na-arụ ọrụ na dipeptides glycosylated iji mepụta hydrogen peroxide nke nwere ike meghachi omume na ndị na-emepụta chromogenic iji mepụta nnabata na 660nm n'ihu peroxidase, mgbe ahụ enwere ike nweta ntinye nke HbA1c site na ịlele nnabata nke. 660nm.Dabere na mkpokọta HbA1c enwetara na ntinye Hb, enwere ike ịgbakọ pasentị HbA1c (HbA1c%).
