Customize This Human Amyloid-beta A4 protein/APP/PN-II ELISA
We manufacture our ELISAs in-house, so we can build a custom version for your study.
- Post-translational modifications (PTMs): Detect modified Amyloid precursor protein (APP), including phosphorylation, acetylation, S-nitrosylation, S-acylation, oxidation, lactylation, sumoylation, ubiquitination, nitration, carbamylation, and more
- Sample types: Validation in your matrix using samples you provide, such as CSF, urine, saliva, lysates, or exosomes
- Also available: More sensitive platforms such as Simoa® and NexaTag®, multiplex panels, bulk lots, and other species when suitable reagents exist
Feasibility varies by target and modification, and we’ll tell you upfront what’s achievable.
