WHITE PAPER

# SubQperior™ The Next Generation *In Vivo* Models

Standard implantation via subcutaneous injection can cause tumor ulceration resulting in early abrogation of your study, leaving you with too short treatment windows and high tumor heterogeneity and resulting in poor statistical value of your results.

## Our Solution

To overcome these challenges, we have developed **SubQperior™**, a superior implantation method for syngeneic and human cell line-derived tumor models. In our SubQperior models tumor cells are implanted via mammary fat pad injection, resulting in

- Larger tumors
- Longer treatment windows
- Homogenous and reliable tumor growth
- Outstanding statistical value
