Abby™ is the next generation chemiluminescence western protein analyzer. She automates protein size separation and immunodetection while delivering analyzed results of 24 samples in 3 hours. Abby saves the time spent in the lab carrying out traditional Western blot steps such as antibody additions, incubations, and washes. She delivers picogram-level sensitivity through chemiluminescence detection and workflow automation.

The Quantikine Human Progranulin immunoassay is a 4.5 hour solid phase ELISA designed to measure Progranulin in cell culture supernates, serum, plasma, saliva, urine, and human milk. It contains NS0-expressed recombinant human Progranulin and has been shown to accurately quantitate the recombinant factor. Results obtained using natural Progranulin showed linear curves that were parallel to the standard curves obtained using th…

Peggy Sue™ lets you separate and analyze proteins by size or charge from 2-440 kDa either by immunoassay or total protein. Got small sample volumes or starting materials? No problem. She uses as little as 0.2 µg/µL of protein in just 5 µL of sample, and runs up to 96 samples in one experiment.

Sally Sue™ lets you separate and analyze proteins by size from 2-440 kDa either by immunoassay or total protein. Got small sample volumes or starting materials? No problem. She uses as little as 0.2 µg/µL of protein in just 5 µL of sample, and runs up to 96 samples in one experiment.

NanoPro™ 1000 gives you all the detailed info you need on your proteins—including characterization of post-translational protein modifications. He also runs the widest pl 3 to 10 gradient and analyzes up to 96 samples at a time to boot. Did we mention he's a conservationist too? Use as few as 25 cells per assay, even when you're characterizing low abundance proteins in limited cell populations.
