FAQs for Complement C3 Antibody (NBP1-32080). (Showing 1 - 2 of 2 FAQ).

  1. I am trying to establish a method to measure mice C3 levels by nephelometry. I would be most grateful if you could provide me with some help, regarding the choice of the Ab. I totally understand that since such a method has never been tried, I do not expect any guaranties. 
    • We have never performed nephelometry in our lab, and do not have a protocol or advice to provide about this application. However, it seems to me that you should choose an antibody that is capable of recognizing its target in its folded conformation. Therefore, I would suggest trying an antibody that has been validated for ICC or IHC.
  2. At what molecular weight can we find the band when run on western blotting with and with out reducing agent?
    • The theoretical molecular weight of Complement C3 is 187kDa. With NBP1-32080, we typically see bands around 180kDa when testing in Western blot under reducing conditions. As we have not tested this antibody in non-reducing conditions we cannot say with certainty at what size you will see the band, but it will most likely be at a higher weight than the band in reducing conditions.
