Overview

The LANCE Ultra Residual Protein A Detection Kit is designed for detection and quantitation of Residual Protein A in cell culture media using a homogeneous TR-FRET (no-wash steps, no separation steps) assay.

The 500 point kit contains enough reagents to run 500 wells in 384-well format, using a 20 µL reaction volume (15 µL of sample). The 10,000 point kit contains enough reagents to run 10,000 wells in 384-well format, using a 20 µL reaction volume (15 µL of sample).

  • No-wash steps, no separation steps
  • TR-FRET technology
  • Sensitive detection
  • High reproducibility
  • Faster time-to-results
  • Easy automation
  • 96-well, 384-well, and 1536-well formats

LANCE and LANCE (Lanthanide chelate excite) Ultra are our TR-FRET (time-resolved fluorescence resonance energy transfer), homogeneous (no wash) technologies. One antibody of interest is labeled with a donor fluorophore (a LANCE Europium chelate) and the second molecule is labeled with an acceptor fluorophore (ULight dye). Upon excitation at 320 or 340 nm, energy can be transferred from the donor Europium chelate to the acceptor fluorophore if sufficiently close for FRET (~10 nm). This results in the emission of light at 665 nm.

Protein A is a 42 kDa protein widely used in affinity chromatography to purify antibodies, most importantly antibody therapeutics. The native form of Protein A from S. Aureus, in addition to many modified recombinant Protein A variants, are used in chromatography. The strong affinity and the high selectivity of Protein A for antibodies lead to an effective removal of host cell proteins. However, Protein A can be leached from columns to contaminate the antibody preparation. Since Protein A could elicit mitogenic or immunological reactions, there are strict regulations as to the acceptable levels of Protein A in antibody preparations. Therefore, there is a current need to quantitate Protein A in antibody preparations with excellent sensitivity and robustness, while maintaining high throughput capabilities.
