Frequently asked questions

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

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?
