Overview

The purpose of this protocol is to provide a detailed method for the creation of an NTA surface on top of a carboxymethylated dextran chip. This protocol specifically focuses on the BiaCore CM5 chip, but could be adapted to other similar chips.

Materials

  • CM5 Chip (New)
  • EDC (50µl)
  • NHS (50µl)
  • Wash Bottle with Deionized Water
  • 3mg/ml NTA-NH2 (100µl)

Definitions

  • EDC: 1-Ethyl-3-(dimethylaminopropyl)cabodiimide HCL
  • NHS: N-Hydroxysuccinimide
  • NTA-NH2: (S)-N-(5-Amino-1-Carboxypentyl)iminodiacetic acid, pH adjusted to pH 8.0

Procedure

  1. To the gold side (concave) of a CM5 chip mix 50μl each EDC and NHS.
  2. Incubate for 20 minutes
  3. Wash chip with DI and then dry with house air.
  4. Add 100 ul of 3mg/ml NTA-NH2 to the chip
  5. Incubate for 30 minutes.
  6. Wash chip with DI and then dry with house air.
  7. Install into the BiaCore and perform NTA Surface Preparation.
