Antibody purification is a common need for increasing the purity yield of

antibodies. In this blog, we are talking about how to troubleshoot points that

enhance antibody purification. Thermo fisher distributors have a clear idea about

it.

Tips For Antibody Purification Troubleshooting

Antibody purification is a critical step in obtaining high-quality antibodies for

various applications. However, it can sometimes present challenges that require

troubleshooting to ensure successful purification. Here are some tips to help

troubleshoot common issues encountered during antibody purification:

● Low Yield:

Ensure proper sample handling and storage conditions to maintain antibody

stability. Optimize the purification protocol by adjusting parameters such as buffer

composition, pH, and salt concentration. Check the column or resin for any

blockages or inefficiencies that may be hindering antibody binding and elution.

Consider alternative purification methods or affinity resins if the current approach

is not yielding satisfactory results.

● Contaminants:

If there is contamination with host cell proteins or nucleic acids, optimize the lysis

and purification buffers to improve specificity. Adjust the wash step parameters to

enhance the removal of impurities without compromising antibody recovery.

Explore additional purification techniques such as size exclusion chromatography

or ion exchange chromatography to further purify the antibody.

● Aggregation or Fragmentation:

Evaluate the antibody stability and optimize the storage conditions to prevent

aggregation or fragmentation. Adjust the pH, temperature, and salt concentration

during purification to minimize these issues. Consider using antibody fragment-

specific purification strategies if fragment formation is a recurring problem.

● Non-Specific Binding:

Optimize the binding and wash conditions to minimize non-specific interactions.

This may involve adjusting pH, salt concentration, or detergent concentration. Use

appropriate blocking agents to prevent non-specific binding during sample

application or column equilibration. Consider the addition of competitor molecules

that can minimize non-specific binding.

● Poor Antibody Quality:

If the purified antibody does not exhibit the desired functional or structural

properties, consider modifying the purification protocol. Review the antibody

production process, including cell culture conditions, harvest time, and purification

timing, to ensure optimal antibody quality. Validate the antibody's functionality

through appropriate assays to confirm its binding specificity and activity.

● Poor Antibody Recovery:

Optimize the elution conditions, including buffer composition, pH, and elution

volume, to maximize antibody recovery without compromising purity. Check for

any losses during the purification process, such as inefficient column packing or

leakage, and address those issues.
