We are interested in your recombinant p21. We have a couple questions on it: 1) what is the isoelectric point of p21 protein? 2) do you have service to modify a fluorescence label onto the protein (like 488)?

Thank you for contacting Abcam regarding ab56278.
Regarding this p21 protein, the isoelectric point has not been determined. Currently we do not have a service for custom conjugation of proteins, however, we do sell simple 3 step kits that can be used to conjugate the protein yourself.
I would like to recommend the FITC EasyLink Conjugation kit, ab102885 along with the Purification kit ab102784 to clean up the protein buffer.
I hope this information is helpful. Please do not hesitate to contact me if you have any additional questions.
