What experimental applications are validated for xanP Antibody?

Based on supplier documentation, xanP Antibody is primarily validated for Western Blot (WB) and ELISA applications . These techniques enable detection and quantification of xanP protein in bacterial samples:

• Western Blot: Provides information about protein molecular weight, expression levels, and potential post-translational modifications

• ELISA: Offers quantitative measurement capabilities with higher throughput potential

While not explicitly mentioned in most product descriptions, experienced researchers might explore using xanP Antibody for immunoprecipitation after careful validation, similar to approaches used with other bacterial protein antibodies .

How should I store and handle xanP Antibody to maintain activity?

Proper storage and handling are crucial for maintaining antibody performance. For xanP Antibody:

• Store at -20°C for long-term preservation
