Vitellogenin - Endocrine Disrupters

Vitellogenin is the precursor of yolk proteins in fish and synthesized under the influence of estrogens. Determination of
Vitellogenin is of importance in evaluating the effects of estrogen and anti-estrogen disruptors as well as in a variety of
physiological studies. The patented TECO Mucus Collection allows the non-invasive, repeated sampling of epidermal
mucus for Vitellogenin determination and offers new opportunities in monitoring programs and to study the dynamic of
endocrine disruptors within the same fish over time. All TECO Vitellogenin ELISAs are suitable for the use in blood,
homogenate and mucus samples.

The TECO Vitellogenin ELISA System is based on 9 different Vitellogenin ELISA tests covering more than 37 fish species,
including standard and ultra sensitive Vitellogenin ELISA tests as well as specific REACH kit configurations designed to
fulfill the specific requirements for endocrine disruptor testing according to REACH and OECD guidelines.
