Application Abreviews Notes
WB Use a concentration of 2.5 µg/ml. Detects a band of approximately 48 kDa (predicted molecular weight: 43 kDa).Can be blocked with Human ERGIC2/PTX1 peptide (ab86285). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • Function

    Possible role in transport between endoplasmic reticulum and Golgi.
  • Tissue specificity

    Ubiquitously expressed.
  • Sequence similarities

    Belongs to the ERGIC family.
  • Cellular localization

    Endoplasmic reticulum-Golgi intermediate compartment membrane. Golgi apparatus > cis-Golgi network membrane. Endoplasmic reticulum membrane. Cytoplasm. Nucleus. Cycles between the endoplasmic reticulum and the Golgi. PubMed:11445006 states that it localizes to the nucleus; PubMed:17980171 shows a partial localization in the nucleus.

I am sorry to hear that you have been experiencing problems using this product in the application that you wish.

In order to assess the quality of our products I would ask that you complete a brief questionnaire relating to the application used. Often it is possible to make suggestions that may help resolve problems experienced using a particular product.

As our Abpromise indicates, in the event that a product is not functioning in the applications/species cited on the product data sheet (and the problem has been reported within 6 months of purchase) we will happily offer a credit note/refund to the value of the product purchased.

Could you provide some further details of the protocol used and complete the following form (attached as a word document for Western blot application).

How have you selected the sequence of siRNA? Have you tried more than one SiRNA sequence? Could you check if the sequence corresponds correctly toERGIC2 protein?
Have you checked the transfection efficiency and optimized the length of time for knockout to take effect?
Have you checked the transfection by fluorescence tags and the knockout by RT-PCR?
Have you used the correct endogenous positive and negative controls? Have you applied scrambled siRNA or standard negative siRNA controls?
Could you please specify the type of the KO (targeted, untargeted, induced KO, tissue specific, KO for fate mapping) and how it was carried out?
Have you checked the KO with Southern blot application?

Thank you for your understanding and co-operation in this matter. I look forward to hearing from you soon and resolving this issue as soon as possible.
