Co-immunoprecipitation (co-IP) Troubleshooting Guide

Elution: Usually accomplished with very harsh conditions such as boiling of the beads in a Reducing SDS-Sample Loading Buffer. When using immobilized antibodies, milder conditions (pH-shift) are applied to avoid disruption of the antibody. In this case, only antigen (antigen and binding partners for co-IP) are eluted free of antibody contamination.

Optimize elution conditions for immunoaffinity purification

• Gentle Ag/Ab Elution Buffer (Product No. 21013 and 21027) is a near-neutral (pH 6.6), high-salt buffer for use when low-pH elution buffers adversely affect antibody and/or antigen function. Depending on the specific affinity interactions involved, this buffer may not be as efficient as the IgG Elution Buffer.

Elution Techniques in Blood Bank

an elution on cells with a negative DAT or sensitized with complement only is a waste of time, effort, and money in most instances. When the DAT is positive with IgG antibody or IgG antibody and complement, an elution may provide significant results. An elution may be indicated to aid in the 1) diagnosis of autoim-
