 Does CytoTest provide custom FISH probes?
Yes! Our sales team is available to provide expert consultation to assist with the design, testing, and manufacture of a custom FISH probe to fulfill your needs. Please contact sales@cytotest.com for more information.
|
How soon after ordering can I expect to receive the FISH probes that I have ordered?
For established customers ordering probes listed in our catalog, requests received by 12PM EST will generally ship the same day with a standard delivery time of 1-3 days for domestic shipments. International shipments are processed on Mondays and Fridays with a delivery time of 3-5 business days. Special packaging requests and overnight/express delivery options are also available please contact sales@cytotest.com for more information.

Does CytoTest provide demo units for its FISH probes?
Yes, we do. Please contact us and let us know which probes you are interested in.
|
What are the package sizes and prices of CytoTest’s FISH probes?
Different probes have different package size and price; it varies from 5 assays, 10 assays to 20 assays per package. Please contact us and let us know the products that you are interested in, and we will provide you with the information. |
Do I need to use antifade to prevent photobleaching of CytoTest’s FISH probes?
We recommend using CytoTest’s DAPI reagent with CytoTest’s FISH probes. CytoTest’s DAPI is designed and optimized to enhance and prolong the signal intensity of CytoTest’s FISH probes.
|
Is there any precaution that we need to pay particular attention to when using your probe?
Please vortex and spin down the sample before use. The CytoTest’s FISH probes can have a certain degree of viscosity. Please make sure to extract and discharge slowly.
|
Are CytoTest’s probes ready-to-use, or do they need to be denatured prior to use?
CytoTest’s FISH probes are ready-to-use; they don’t require denaturation before use. However, CytoTest’s probes can withstand repeated denaturation; their performance will not diminish. We recommend that users equilibrate the probes at room temperature in darkness for 20-30 minutes prior to use.
|
Are CytoTest’s FISH probes directly labeled or indirectly labeled with fluorescent dye?
CytoTest’s probes are directly labeled target DNA fragments with fluorophore.
|
Can I dilute CytoTest’s FISH probes?
CytoTest’s probes are rigorously designed and quality tested to assure they meet the highest standard. We therefore do not suggest that users dilute CytoTest’s probes for FISH experiments, and we can’t guarantee the outcome of FISH experiments when using diluted probes.
|
What is the difference between terminal band probes and subtelomeric probes?
Our terminal band probes are prepared from microdissected chromosome terminal bands, so they cover much larger chromosome areas than the subtelomeric probes, which are derived from genomic DNA clones typically covering a range of several hundred kb within the subtelomeric regions.
