Polyclonal antibody HA.11 was raised against the twelve amino acid sequence CYPYDVPDYASL.
Phosphate-buffered solution + 0.03% thimerosal.
The antibody was purified by affinity chromatography.
1.0 mg/mL
Storage & Handling
The antibody solution should be stored undiluted between 2°C and 8°C. Please note the storage condition for this antibody has been changed from -20°C to between 2°C and 8°C. You can also check your vial or your CoA to find the most accurate storage condition for this antibody.

ChIP, ICC, Purification - Reported in the literature, not verified in house

Recommended Usage

Each lot of this antibody is quality control tested by Western blotting.

The optimal working dilution should be determined for each specific assay condition.
WB: 1:1,000*
IP: 1:150

Application Notes

This antibody is effective in immunoblotting (WB) and immunoprecipitation (IP) of tagged proteins.

*Our Posi-Tag Control Protein (931301) can be used as a helpful positive control for this antibody.

This antibody recognizes the same hemagglutinin flu epitope YPYDVPDYA as the monoclonal antibody, HA.11 clone 16B12. This polyclonal antibody facilitates epitope tag experiments in murine systems and is useful in experiments involving two proteins labeled with two different tags.

This product may contain other non-IgG subtypes.
