7.0 EXPERIMENTAL DESIGN AND METHODOLOGY
The test article will be tested at a minimum of five dose levels along with appropriate neeativc and positive controls with tester strains TA98. TA100. TAI535. TA97A and P2 i/irA tpKMIOl) with and without S9 activation. All dose levels of test article, negative controls and positive controls will be plated in triplicate.
Solubility* Determination
1
Unless the Sponsot has indicated the test article vehicle, a solubility determination will be conducted to determine the maximum soluble concentration or workablesuspension up to a maximum of 500 mg ml. Vehicles compatible with this test Svstem, in order of preference, include but arc not limited to: deionized water (CAS 7732-18-51. Jimethylsullbxidc (CAS 67-68-5). ethanol (CAS 6-4-17-5) and acetone (CAS 67-64-1) The vehicle of choice will be the solvent, selected in order of preference, that permits preparation of the highest vvorkable'solubli- slock
concentration, up to 500 ntg ml
3 Preliminary Toxicity Assay to Select Dose Levels
Selection of dose levels for the mutagenicity assay will be based upon the toxicity
and precipitation profile of the lest article assessed in a preliminary toxicity assay
Ibis preliminarv assay will be conducted by exposing TA98. TAIOO. TAI-VP.
UV'-A and WP2 air A (pKMIOl) to negative controls and to at least eight
concentrations of lest article, one plate per dose level, in both the presence and
absence of S*>activation Unless indicated o.herwisc by the Sponsor, the highest dose
will be the highest workable concentration in the vehicle of choice but not to exceed
' ini' plate loxicilv will be evaluated as a decrease in the number of revertanl
colonies per plate and or a thinning or disappearance ol the bacterial background

The presence of the pKMIOl plasmid will be confirmed for tester strains TA98. TAI00 and TA97A bv demonstrating resistance to ampictllin.
On the day of use in the mutagenicity assay, the E coli tester strain cultures will be
checked lor the presence of the rnrA mutation by demonstrating sensitivity to ultraviolet light. The presence of the pKMIOl plasmid will be confirmed for tester strain WP2 inrA (pKMIOl) by demonstrating resistance to ampicillin.

8.1 Tester Strain Integrity
To demonstrate the presence ol the r/n mutation, all S. lyphim uriunt tester strain
cultures must exhibit sensitivity to crystal violct. To demonstrate the presence of the
rrvrB mutation, all .S' ryphinuirium tester strain cultures must exhibit sensitivity to ultraviolet light. To demonstrate the presence ot the irvrA mutation, nil E. coli tester
strain cultures must exhibit sensitivity to ultraviolet light. To demonstrate the presence o f the pKMIOl plasmid R-factor. tester strain cultures o f TA98. TAIOO. TA97A and WP2 nvrA (pKMIOl) must exhibit resistance to ampicillin.
8.2 Spontaneous Revertant Background Frequency-
Based on historical control data, all tester strain cultures must exhibit characteristic number of spontaneous revertants per plate in the negative controls (vehicle). Thc mean revertants per plate must be within the following ranges (inclusive): TA98, 10 - 50; TAIOO, 80 - 240; TAI535.5 - 45; TA97A. 80 - 240; WP2 rA (pKMIOl). 150 . 380.
8.3 Tester Strain Titers
To ensure that appropriate numbers o f bacteria are plated, all tester strain culture liters must be equal to or greater than 0.3x10* cells per milliliter.
8.4 Fositive Control Values
Each mean positive control value must exhibit at least a three fold increase over the respective mean negative control value (vehicle) for each tester strain.
8.5 Toxicity
A minimum of three non-toxic dose levels will be required to evaluate assay data. A dose level is considered toxic if it causes a >50% reduction in the mean number of revertants per plate relative to the mean negative control value (this reduction must be accompanied by an abrupt dose-dependent drop in the revertant count) or a reduction in the background lawn. In the event that fewer than three non-toxic dose levels are achieved, the affected portion of the assay will be repeated with an appropriate change in dose levels.
