Our Abpromise guarantee covers the use of ab88644 in the following tested applications.

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

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 32 kDa (predicted molecular weight: 32 kDa).
Flow Cyt Use at an assay dependent concentration. ab37355-Mouse polyclonal IgG, is suitable for use as an isotype control with this antibody.


  • FunctionTRAP proteins are part of a complex whose function is to bind calcium to the ER membrane and thereby regulate the retention of ER resident proteins. May be involved in the recycling of the translocation apparatus after completion of the translocation process or may function as a membrane-bound chaperone facilitating folding of translocated proteins.
  • Sequence similaritiesBelongs to the TRAP-alpha family.
  • DomainShows a remarkable charge distribution with the N-terminus being highly negatively charged, and the cytoplasmic C-terminus positively charged.
  • Cellular localizationEndoplasmic reticulum membrane.
