3-Dimensional Cell Culture

Proprietary methods for optimized generation & therapeutic screening on spheroids in a variety of cell types.

Stable Cell Line Generation

Generation of stable cell lines through chemotherapy resistance, viral transduction, and other methods.

Cell Migration Assays

Real-time automated imaging of kinetic cell migration, invasion assays, and other cell motility read-outs.

Technical Capabilities

Standard and high-throughput confocal microscopy with quantitative read-outs and corresponding high-resolution images.Instruments have capabilities for brightfield and multicolor immunofluorescence imaging to handle your experimental needs. Data is processed by a team of experts capable of creating novel masking analysis to probe for unique and novel targets.

Ichor’s team has extensive experience optimizing protocols for spheroid generation. The dimensions of the spheroids are robustly characterized with our high-content imaging cytometers, ensuring batch-to-batch consistency. The meticulously characterized spheroids allow for a high degree of experimental reliability in our in-vitro and in-vivo assays.

Have Confidence In Your Data


When confirming molecular mechanisms, it’s important to verify the findings through multiple techniques. The above data set represents a standard package we provide customers. In this example we are assessing the nuclear localization of an oncology target, as a function of drug concentration.

Through western blot densitometry, quantitative imaging cytometry, and confocal microscopy, we show three identical trends between the three different techniques. Our goal is to help you achieve compelling data sets that move the needle forward on your research.

Spheroid Examples


Glioblastoma Spheroid Screening

Examine your molecule in one of our established in-vitro 3D tumor models. Our high-throughput imaging cytometers can screen hundreds of conditions simultaneously in comparison to current standards of care.

We can generate spheroids of precise dimensions, and have our surgical team implant them into our catalog of in-vivo models.


Optimized Cellular Targeting of Biologics

Our high throughput cell penetrating peptide (CPP) screens are designed to optimize cellular selectivity and organelle tropism based on target cell membrane physicochemistry and intracellular trafficking machinery.

Frequently Asked Questions

Questions we often get from customers

Ichor has a wide variety of standard and specialized cell assay services. However, our specialty is generating custom assays and approaching scientific problems with “out-of-the-box” thinking. Customers frequently approach us because they could not find service providers willing to customize assay parameters.

All raw data and images will be shared through your preferred electronic medium. We will also send presentations containing annotated data and experimental procedures.

Experimental timelines can vary depending on the design. We can typically turn around data packages in 2-3 weeks from the time of receiving reagents.

If you are unsure which cell based assay to choose, one of our experts will be happy to discuss logical and cost effective options to best answer your scientific questions.
