Carrier ampholytes pI markers
17 listings from 8 suppliers
Japanese name: 両性担体・pIマーカー（IEF試薬）
Carrier ampholytes form a stable pH gradient in isoelectric focusing (IEF) and imaged capillary IEF (icIEF), and pI markers fix positions along that gradient. They are used to assess charge heterogeneity and acidic and basic isoforms of antibodies. Buyers match the reagents to their method (gel IEF or capillary IEF), choose a wide or narrow pH range that brackets the target pI, and compare synthetic against protein-based markers, MS compatibility and lot-to-lot reproducibility. The list that follows gives product names, makers, and Japanese sellers.
