Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 53 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • Function

    Provides CDP-diacylglycerol an important precursor for the synthesis of phosphatidylinositol (PtdIns), phosphatidylglycerol, and cardiolipin. Overexpression may amplify cellular signaling responses from cytokines. May also play an important role in the signal transduction mechanism of retina and neural cells.
  • Tissue specificity

    Expressed in adult tissues such as placenta, brain, small intestine, ovary, testis and prostate. Highly expressed in fetal kidney, lung and brain. Lower level in fetal liver.
  • Pathway

    Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 3/3.
  • Sequence similarities

    Belongs to the CDS family.
  • Cellular localization

    Endoplasmic reticulum membrane. Cytoplasmic aspect of the endoplasmic reticulum.

Thank you again for your call yesterday, and also for your patience while I have looked through some literature as well as through the Western blot images.

I do have a couple of additional questions to clarify this data, as I haven't worked with the CDS1 protein in my own research. Is the human lymphocyte mitochondrial lysate a negative or positive control? I have found some data indicating that CDS1 is present in the mitochondria but expression in the hematopoetic line seems to be very low. Also, do you expect high expression of the protein in heart tissue?

From the images,I agree thatthe antibody is non-specifically binding to several proteins and might be binding to a specific CDS1 protein in lane 2 and very weakly lanes 6 and 6 around 50 kDa, though I'm not sure why there is such as difference between the band in lane 2 and the other heart samples. Were these samples taken from different animals, or is there anything else that might explain a difference of CDS1 expression?

We do guarantee all of our products to work in tested species and applications, and though we have not tested ab84019 with rat samples, we do guarantee it to work with positive control samples from human origin. I would be happy to send a replacement like ab88121 or alternatively issue a credit or refund if that is the case.

I look forward to hearing from you, and I'm sorry I don't have any specific recommendations to fix the issue at this time. Please let me know if you have any questions or if there is anything else that we can do for you, and feel free to give me a call if you prefer to discuss this over the phone (you can call 888-772-2226 and just ask to speak to me).

Thanks for your call today and for letting us know about the trouble with ab84019.

As we discussed, please forward me an image of your blot when you get a chance. I'll check the literature and our protocol for this antibody and see if there 's anything we can do to improve these results.

I look forward to hearing from you. Please let me know if you have any questions or if there is anything else that we can do for you.
