Capillary Isoelectric Focusing (cIEF) System

毛细管等电聚焦(cIEF)系统

Charge-variant profiling for antibodies and biosimilars needs fine pI resolution in minutes. This cIEF system images the whole column with 280 nm UV (single-point UV also available) through neutral-coated 50–100 µm capillaries. Focusing at up to 30 kV takes about 5–10 min, resolving about 0.05 pI units across pH 3–10 depending on ampholytes.

Detection
Whole-column UV imaging at 280 nm (or single-point UV)
Capillary coating
Neutral (EOF-suppressed)
Capillary internal diameter
50–100 µm
Capillary length
approx. 5–10 cm (imaging) or 30 cm

Product Description 产品描述

Charge-variant profiling for antibodies and biosimilars needs fine pI resolution in minutes. This cIEF system images the whole column with 280 nm UV (single-point UV also available) through neutral-coated 50–100 µm capillaries. Focusing at up to 30 kV takes about 5–10 min, resolving about 0.05 pI units across pH 3–10 depending on ampholytes.

Highlights

  • Whole-column imaging skips mobilisation
  • Short focusing time per sample
  • Supports forced-degradation studies
  • Choose imaging or single-point detection

Applications

  • Monoclonal antibody charge variant profiling
  • Biosimilar comparability studies
  • Stability and forced-degradation studies
  • pI determination of recombinant proteins
