Frequently asked questions

What delivery time frame can we expect for a custom formulation/conjugation request?

  • Expected delivery time of a custom conjugation or formulation is approximately one month. Delivery times may be shorter or longer depending on the generation time required for raw materials.


Are larger volume requests deliverable in a single larger vial, or multiple smaller vials?​

  • In most cases we are able to offer the flexibility of either a single larger vial or multiple smaller vials depending on your preference.


May we send Abcam our own antibody for a custom conjugation?

  • ​​While we are unable to offer conjugation of non-Abcam antibodies, we have an extensive range of conjugation kits available for use.


What level of validation is conducted to ensure a custom conjugation or formulation was successful?

  • For custom conjugations, the dye-to-protein ratio (D:P ratio) is used for standard validation. Further conjugate validation can be performed upon request. All custom formulations are batch-validated according to the requested conditions.
