Human estradiol E2 radioimmunoassay kit
The ESTR-US kit is a radioimmunoassay of human estradiol (E2) for the evaluation, diagnosis, and monitoring of many fertility and oncology disorders.
For Research Use Only, not for use in diagnostic procedures.
Assess ovarian function in women
Assess estradiol during the use of clomiphene or hMG for diagnostic purposes (exploration of amenorrhea or anovulation)
Assess occurrence of pregnancy
Monitor ovulation and in-vitro fertilization
Evaluate feminization in men, including gynecomastia
- COMPATIBLE WITH A DAILY FOLLOW-UP OF ASSAYS
- ACCURATE ASSAY OF HIGH VALUES WITHOUT DILUTION
The principle of the assay is based on competition between iodine-125 radiolabeled estradiol and estradiol contained in the samples for a fixed and limited number of anti-estradiol polyclonal antibody binding sites adsorbed onto the tube walls.
Two possible assay procedures:
1- female sera under ovulation induction: 1h30 at RT / shaking;
2- other applications 2h30 at RT / shaking.
Working range: 4 – 5000 pg/mL (GCMS) [Estradiol in pmol/L] = [Estradiol in pg/mL] x 3.67
Sample: serum or plasma – 100 µL
Analytical sensitivity: 4 pg/mL
Functional sensitivity: 8 pg/mL
