We provide analysis of both mouse and human cells. Other species are available on request. In the past, species karyotypes we have performed include pig karyotype, rat karyotype, and camel karyotype.
For each species, there are two levels of service available:
(1) Cells growing in culture (which we process for analysis),
(2) Cells already processed and fixed in your lab (we provide a detailed protocol).
The results are returned within 15/17 business days for human samples and within 20/22 business days for mouse samples. At busy times, lead times can be longer, please ask for details on reporting times when sending your samples for analysis.
All services aim to provide karyotype analysis of 20 G-banded metaphase spreads from a single cell culture sample. If fewer than 20 cells are found in the sample provided, as many cells as possible will be analyzed. At least one high-quality image of a representative karyotype is provided which is suitable for publication. In the event karyotypic abnormalities are found, additional figures will be provided. If complex mosaic karyotypes are found, fewer than 20 cells may be analyzed.
Please note that for cancer cells and in any cases where very complex, unstable karyotypes are observed, a full karyotype for a single cell will be provided. Additional charges will apply to any additional cell analysis.
Results are returned via email.
If you have any questions, please contact us by email firstname.lastname@example.org or using the form below. We will respond within one business day.
Please note, we do not offer clinical services for patients, and the service is not available for intermediaries offering a karyotype service.
We are often asked what constitutes a normal report? Here are some thoughts on the subject:
1. Since we are typically searching for abnormalities associated with cell culture, we report every cell with a structural abnormality.
2. We would most likely not report cells with a single chromosome trisomy or monosomy as these could be found due to slide preparation (over-spreading).
3. 10% mosaicism for structural or numerical abnormality would be excluded when practical in all instances.
4. Cell lines with multiple cells with the same or different related abnormalities would be classed as cytogenetically abnormal.
5. We would not assign the cell line as abnormal if an abnormality was found in a single cell only.
Please note that for customers in the US, the service is only available for fixed samples.
