The PathHunter® ProLabel Detection Kit is for use with PathHunter Cell Lines expressing ProLabel® (PL) or ProLink™ (PK) expression or cloning vectors. The kit measures the total amount of ProLabel- or ProLink-tagged protein expressed in cells. Functional assays using PathHunter Cell Lines expressing both a ProLabel- or ProLinktagged protein and EA require the PathHunter Detection Kit (93-0001). The assay can be used in both 96-well and 384-well microplate formats.
