SEND Example.In vitro Neutral Red Cytotoxicity Assay

This example shows a report table, trial design and results data for the in vitro Neutral Red Uptake Cytotoxicity Assay in example study 123.

The following shows example data for study 123 in a report table. This report includes summary statistics (e.g. Average, Standard Deviation, Coeff. Var.) for each plate and an EC50 value for the entire assay. The grey cells in plate 1 are cells that do not contain the CHO Hamster cells.

Rows 1-20:	Show the test conditions for the set with a short name or SETCD value of CSC-50b. The sponsor chose this value to represent plate number 1, well number 1, with a concentration of 50 µg/mL of Cigarette Smoke Condensate as shown in the report table for study 123.
Row 17:	Shows the value for STRAIN/SUBSTRAIN is NO STRAIN because the well is a media only well, having no CHO Hamster cells.
Rows 21-40:	Show the test conditions for the set with a short name or SETCD value of CSC-50. The sponsor chose this value to represent plate number 1, well number 2, with a concentration of 50 µg/mL of Cigarette Smoke Condensate as shown in the report table for study 123.
Rows 41-60:	Show the test conditions for the set with a short name or SETCD value of CSC-50. The sponsor chose this value to represent both wells numbered 7 in plate number 1 and 2, with a concentration of 110 µg/mL of Sodium Laurel Sulfate as shown in the report table for study 123
