The p62 (sequestosome 1) and NBR1 ELISA kits provide a quantitative, immunometric detection method for measuring autophagy in human, rat, and mouse cell lysates. These assays measure as little as 66 or 100 pg/mL of NBR1 or p62, respectively, and provide fully quantitative results. With the ability to analyze up to 40 samples in duplicate in less than three hours, these kits meet the needs for rapid, high-throughput analysis. The p62 and NBR1 ELISA kits are complete, flexible, and thoroughly validated. They are supplied with a precoated microtiter plate and liquid color-coded reagents. The break-apart strip plate design provides flexibility—not having to run all 96-wells at once.
