Target

  • Function

    Involved in the association of MHC class I with transporter associated with antigen processing (TAP) and in the assembly of MHC class I with peptide (peptide loading).

  • Tissue specificity

    Neutrophils, mostly in fully differentiated cells.

  • Sequence similarities

    Contains 1 Ig-like C1-type (immunoglobulin-like) domain.

  • Domain

    The N-terminus is required for efficient association with MHC class I molecule and for a stable interaction between MHC I and calreticulin. Binding to TAP is mediated by the C-terminus region.

  • Cellular localization

    Endoplasmic reticulum membrane.

    Answer

    I'm sorry to hear your customer is having problems with ab13518 and thank him for taking the time to give us protocol details. We have not received any complaints regarding this antibody and are confused by the complaint form: the customer mentions immunoprecipitation as the application used for this antibody. However, from the protocol it appears that the immunoprecipitation step was done with the competitor antibody and no details for the Ip were provided. If this is correct we suggest testing our antibody on lysates of HeLa cells by western blotting. A 1:1,000 dilution of ab13518 is sufficent for detection of Tapasin in 20µg of HeLa cell lysate and will determine whether the antibody is faulty. Thank you for sending us an image, however it is unclear to us what it shows as there is no legend. Is it comparing two immunoprecipitations with different antibodies and reprobe with the same antibody? We would like to emphasise to use an adequate lysis buffer (e.g RIPA buffer) with a cocktail of protease inhibitors to prevent the degradation of the protein rather than PBST. Samples should be mixed with loading buffer (containing SDS and betamercaptoethanol) and boiled for 5min at 95C to unfold and denature the protein for adequate recognition. As this information was not present on the form we wish to confirm this recommendation. I apologise for asking clarification of the problem. We have updated our questionnaires for our distributors and can send you those so that we can obtain the maximum information from the customer initially and help the customer as quickly as possible (for example we have an immunoprecipitation specific questionnaire). Please let us know which e-mail address you would like the forms to be sent to you and I will send those immediately. Thank you for your patience, we look forward to hearing from you,
