Do you provide control proteins for use with the PhosphoProtein Purification Kit?
FAQ ID -596

No, we do not currently provide controls for this kit. BSA can be used as a negative control, since it is not phosphorylated. Use only high-purity grade BSA without any residual phopholipids.

We recommend casein or ovalbumin as a positive control. These proteins can be detected using our PhosphoSerine and PhosphoThreonine Antibody.
