    Test No. 457: BG1Luc Estrogen Receptor Transactivation Test Method for Identifying Estrogen Receptor Agonists and Antagonists

    This Test Guideline describes an in vitro assay, which provides concentration-response data for substances with in vitro ER agonist and antagonist activity. The test system utilises the BG1Luc4E2 cell line derived from a human ovarian adenocarcinoma and stably transfected with a ER responsive luciferase reporter gene. This cell line can evaluate TA mediated by ER alpha and ER beta. The cells are plated into 96-well plate and

    Test No. 443: Extended One-Generation Reproductive Toxicity Study

    This Test Guideline is designed to provide an evaluation of reproductive and developmental effects that may occur as a result of pre- and postnatal chemical exposure as well as an evaluation of systemic toxicity in pregnant and lactating females and young and adult offspring. In the assay, sexually-mature males and females rodents (parental (P) generation) are exposed to graduated doses of the test substance starting 2 weeks before

    Test No. 460: Fluorescein Leakage Test Method for Identifying Ocular Corrosives and Severe Irritants

    This Test Guideline describes an in vitro assay that may be used for identifying water soluble ocular corrosives and severe irritants as defined by the UN Globally Harmonized System of Classification and Labelling, Category 1. The assay is performed in a well where a confluent monolayer of Madin-Darby Canine Kidney (MDCK) is used as a separation between two chambers. It uses a fluorescein dye as marqueur. The test substance has the

    Test No. 305: Bioaccumulation in Fish: Aqueous and Dietary Exposure

    This Test Guideline describes a procedure for characterising the bioconcentration potential of substances in fish, using an aqueous (standard and minimised tests) or dietary exposure, under flow-through conditions (but semi-static regimes are permissible). Independent of the chosen exposure method, the bioconcentration fish test test consists of two phases: exposure (uptake) and post-exposure (depuration). During the uptake phase

    Test No. 455: Performance-Based Test Guideline for Stably Transfected Transactivation In Vitro Assays to Detect Estrogen Receptor Agonists

    This Performance-Based Test Guideline (PBTG) describes in vitro assays, which provides the methodology of Stably Transfected Transactivation to detect Estrogen Receptor Agonists (ER TAs). It comprises mechanistically and functionally similar test methods for the identification of estrogen receptor agonists and should facilitate the development of new similar or modified test methods. The two reference test methods that provide the

    Test No. 114: Viscosity of Liquids

    This Test Guideline describes methods to measure the viscosity of liquids. Most of the methods listed are appropriate for the investigation of Newtonian liquids. The measurement of non-Newtonian liquids is possible with the rotational viscometer. Viscosity measurements are carried out according to five methods: the capillary viscometer, the flow cup, the rotational viscometer, the rolling ball viscometer and the drawing ball

    Test No. 109: Density of Liquids and Solids

    This Test Guideline lists methods for determining the density of liquids and solids, giving only a succinct description of them. The density of a substance is the quotient of its mass and its volume and is expressed in SI units as kg/m3 at a specified temperature. Several methods are for liquid substance only: hydrometer, immersed body method (both are buoyancy methods) and oscillating densitometer. These methods are applicable to

    Test No. 229: Fish Short Term Reproduction Assay

    This Test Guideline describes an in vivo screening assay for fish reproduction where sexually mature male and spawning female fish are held together and exposed to a chemical during a limited part of their life-cycle (21 days). The short term reproduction assay was validated in the fathead minnow (Pimephales promelas) and this is the recommended species. The assay is run with three test chemical concentrations and the

    Test No. 211: Daphnia magna Reproduction Test

    The test method described in this Test Guideline assesses the effect of chemicals on the reproductive output of Daphnia magna Straus. To this end, young female Daphnia are exposed to the test substance added to water at a range of concentrations (at least five). For semi-static tests, at least 10 animals at each test concentration and for flow-through tests, 40 animals divided into four groups of 10 animals at each test
