Frequently Asked Questions
What does ExactAb? mean?
ExactAb? indicates the product has been validated for use in rigorous antibody validation workflows. Validation may include positive/negative control samples, signal-to-noise testing, and protocol-specific QC. Lot-specific test data is published on the Certificate of Analysis where available.
How should this product be stored?
Store at 2–8 °C, protected from light. Do not freeze. Freezing may cause irreversible damage to this material.
What does Validated mean?
Validated indicates the product has been validated for use in rigorous antibody validation workflows. Validation may include positive/negative control samples, signal-to-noise testing, and protocol-specific QC. Lot-specific test data is published on the Certificate of Analysis where available.
How is this product shipped?
This product ships chilled on wet ice. Unpack on arrival and transfer it to the storage condition stated above.
What documentation is provided?
Available product documentation, including Certificates of Analysis (COA), Safety Data Sheets (SDS), and specification sheets, is shown in the product document area. Document availability and access follow the current site policy.
Which species reactivity has this antibody been validated against?
Validated reactivity is listed on the PDP and on each lot's datasheet. We validate against the most commonly tested species for the target (CD8 alpha Rat mAb (AF488)); cross-reactivity in untested species may exist but is not guaranteed. Contact technical support for specific species inquiries.
