Specifications

Our Abpromise guarantee covers the use of ab134446 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Applications

    SDS-PAGE

    Functional Studies

    Inhibition Assay

  • Form

    Liquid

  • Additional notes

    Upon freezing, a faint precipitate may form which contains htrA4. This precipitate was shown to contain catalytically active htrA4 in a casein digest. Therefore, we recommend vortexing ab134446 before use.
