  • General notes

    The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

Target

  • Function

    Transcriptional activator required for lipid homeostasis. Regulates transcription of the LDL receptor gene as well as the cholesterol and to a lesser degree the fatty acid synthesis pathway (By similarity). Binds the sterol regulatory element 1 (SRE-1) (5'-ATCACCCCAC-3') found in the flanking region of the LDRL and HMG-CoA synthase genes.

  • Tissue specificity

    Ubiquitously expressed in adult and fetal tissues.

  • Sequence similarities

    Belongs to the SREBP family.
    Contains 1 basic helix-loop-helix (bHLH) domain.

  • Post-translational
    modifications

    At low cholesterol the SCAP/SREBP complex is recruited into COPII vesicles for export from the ER. In the Golgi complex SREBPs are cleaved sequentially by site-1 and site-2 protease. The first cleavage by site-1 protease occurs within the luminal loop, the second cleavage by site-2 protease occurs within the first transmembrane domain and releases the transcription factor from the Golgi membrane. Apoptosis triggers cleavage by the cysteine proteases caspase-3 and caspase-7.

  • Cellular localization

    Nucleus and Endoplasmic reticulum membrane. Golgi apparatus membrane. Cytoplasmic vesicle > COPII-coated vesicle membrane. Moves from the endoplasmic reticulum to the Golgi in the absence of sterols.

    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffers EDTA pH 9.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.

Question

To whom may concern, I'd like to know what is the diluent of the ab28482 product (lot 859967). Could it be in ultrapure water or PBS? Best regards.

Read More
Answer

Thank you for contacting us. Indeed, I can confirm that the storage buffer of anti-SREBP2 antibody ab28482 (lot859967) is PBS containing 0.05% sodium azide and 1 mg/ml BSA as a stabilizing protein. This is needed to reduce the risk of degradation by proteases during long term storage. So if you would like to dilute this antibody further, I would recommend using PBS including BSA. In order to dilute the antibody for applications like western Blotting, any suitable buffer like dilution buffer with or without blocking protein (BSA or milk) can be used, as for example PBS or TBS, either with Tween 20 or without. This needs to be determined for the particular experimental setting. I hope this information is helpful. Please do not hesitate to contact us again with any other questions.

Submitted Oct 20 2010

Question

Ab28482 was raised to the synthetic peptide AISWLQGDDAAVRSH, corresponding to amino acids 843-857 of Mouse SREBP 2. Depend on this, the n-terminal transcriptional form SREBP 2 will not be recognized by this antibody. why it can recognize both forms of SREBP 2? In our study,i want to find an antibody recognize both forms SREBP2 in rats.

Answer

Thank you for your enquiry. Regarding ab28482 (SREBP 2), this product does detects an ~68 and 120 kDa protein representing SREBP 2 in mouse and rat liver samples as well as rat kidney samples. A predominent band at ~68 kDa (active cleaved site) is seen and a band at ~120 kDa (inactive precursor) may not be seen or it may be diminished. Yes, the smaller band is the cleaved active site of SREBP 2. Please let me know if I can assist you further.
