PENGARUH WAKTU DAN SUHU INKUBASI PADA OPTIMASI ASSAY KIT RIA MIKROALBUMINARIA
Sari
Penentuan kadar albumin dalam jumlah mikro dalam urin pasien sangat penting dilakukan untuk deteksi dini mikroalbumin sebelum menjadinephropathy(gagal ginjal). Penentuan kadar mikroalbumin tersebut menggunakan teknik radioimmunoassay(RIA) dengan kit RIA Mikroalbuminuria. Kit RIA yang baru harus memberikan kinerja assayyang baik, maka setelah diproduksi komponen kit RIA Mikroalbuminuria yang memenuhi syarat perlu dilakukan rancangan assayyang tepat agar diperoleh kondisi assayyang optimum. Telah dilakukan optimasi rancangan assaykit RIA Mikroalbuminuria untuk memperoleh waktu dan suhu inkubasi yang terbaik, yaitu variasi waktu inkubasi 1 jam, 3 jam, 5 jam dan 18 jam dan suhu inkubasi 4°C, 25°C dan 37°C. Protokolassayyang optimum dicapai dengan inkubasi selama 3 jam pada 37°C, yang menghasilkan % ikatan maksimum sebesar 52% dan ikatan non spesifik (NSB) cukup rendah 0,15%. Kit RIA Mikroalbuminuria ini stabil memenuhi syarat %B/T dan %NSB dan dapat dipertahankan selama 8 minggu.

Determination of albumin content at micro quantity in a patient urine is very important for an early detection of microalbuminuria before a nephropathy (kidney failure) state to occure. Determination of albumin content in a patient urine is by radioimmunoassay technique using microalbuminuria RIA kit. In a production of a new. icroalbuminuria RIA Kit, a good assay performance should be quaranteed, therefore after RIA reagent that fulfil the required quality were obtained, an optimum assay condition should be esigned. Optimization for assay design of microalbuminuria RIA kit have been carried out in order to obtained the best incubation time and temperature. Incubation time and temperature investigated were 1 hour, 3 hour, 5 hour and 18 hour and 4°C, 25°C dan 37°C respectively. The optimum assay protocol was achieved by 3 hour incubation at 37°C, resulting a high maximum binding of 52% and very low non spesific binding (NSB) of 0,15% respectively. The microalbuminuria RIA kit was stable and comply the required %B/T and %NSB up to 8 weeks.
