Director, Scientific Business Development
Rockland can demonstrate that an accepted method provides meaningful data for specified conditions.
• Matrix effects• Process specific samples evaluations• Suitability of the protocol under actual performance conditions
• Comprehensive experimental performance • Evaluation and documentation of the assay quantitative performance
Assay Validation Performance Parameters
Rockland offers quality control testing on reagents from individual production lots. This ensures purity, activity, stability, and performanceQC testing is available on:• Raw materials • Unprocessed bulk • Purified bulk • Filled finished products Examples of Immunoassays
Plates were coated with a serial dilution of antigen and probed with several capture antibodies. The lead capture antibody has a limit of detection below 100 pg.
Cell-based fluorescent ELISA
Adherent epithelial cells were fixed onto a plate and probed with primary antibody anti-GAPDH and detected by a secondary DyLight 488 coupled antibody.
Comparison of several blocking buffers and time of blocking to optimize the ratio signal to noise.
The result for this assay was that background and variability of blocker 1 incubated at room temperature for 2 hours were lowest compared to other blockers.
