PDX Cell Line Assays
In addition to more than 260 commercial human tumor PDX cell lines, we offer more than 75 proprietary cell lines derived from our PDX models, and this number continues to grow. Each cell line is fully characterized with selected clinical data and comprehensive molecular data for the originating tumor, and have been characterized by their sensitivity for up to 240 reference agents.

In Vitro PDX Assays
Figure 1: Diagram of 2D In Vitro PDX assays. The patient-derived tumor material or PDX cell lines are cultured into a monolayer and tumor growth is monitored to test effects of compounds in PDX cell line assays.
By using tumor cell lines derived from our portfolio of PDX models, we retain characteristics such as expression and mutation profiles; this creates “matched pairs” of xenografts and corresponding cell lines. This allows you to improve translation by using the same models for your in vitro cell line assays, ex vivo and in vivo efficacy studies.

Frequently Asked Questions (FAQs) in In Vitro PDX Assays Research
What is a patient-derived xenograft?
Patient-derived xenografts (PDX) are models of cancer where the tissue or cells from a patient’s tumor are implanted into an immune deficient or humanized mouse. PDX assays and models simulate human tumor biology allowing for natural cancer progression, and offer the most translational research model for evaluating efficacy.
Determine which PDX model is best for your studies
Does in vitro data correlate with in vivo PDX models?
Data collected in cell line assays such as in vitro PDX assays can be used to select PDX (patient dervived xenograft) models for subsequent in vivo efficacy studies.
