RUNX2 is a transcription factor that mediates the expression several downstream proteins, which affect osteoblast differentiation and mitotic progression. It also is important in monocyte activation, as it is upregulated in response to LPS infection. Through interaction with Twist 1 and Twist 2, RUNX2 regulates osteocalcin transcription, following parathyroid hormone signaling for bone loss repair. Ossification in skeletal formation is also partially regulated through RUNX2. Essentially, this transcription factor is responsible for many developmental and repair mechanisms in bone and collagen.

FAQs for RUNX2/CBFA1 Antibody (NBP1-77461). (Showing 1 - 2 of 2 FAQs).

  1. We would like an anti-RUNX2 for IHC-P which share cross reactivity with Rat, but not with Human.
    • We don't have any data for our RUNX2 antibodies that confirms they will NOT detect the human protein. When we can confirm that an antibody will not react with a certain species, we display a (-) sign on the datasheet. Otherwise, if the species is not listed it means that it has not been tested.
  2. I want to chase Runx2/CBFA1 antibody (NBP1-77461). Does it work with frozen section?
    • Our lab has never tested this antibody in IHC-Fr (frozen sections). NBP1-77461 has only be validated in ICC/IF and IHC-P. Therefore we don't know whether this antibody can produce the positive results in your experiments. However our experiences tell us that, as a general rule, the antibodies that can be used in IHC-P, they are likely to produce the positive results in IHC-Fr after some optimizing experiments. If you indeed use NBP1-77461 in IHC-Fr, you will be automatically qualified for our Innovator's Reward that earn a free antibody from us.
