FAQs for GMF-beta Antibody (NBP1-89755). (Showing 1 - 2 of 2 FAQs).
I am interested in purchasing this antibody (glial maturation factor-beta) but I have a trivial question before. As far as I know, gmf-beta has being described as an astrocytic factor, therefore I am quite puzzled observing the IHC that you reported. In fact, the signal appear concentrated in the soma (or nucleus) of some neurons. How do you justify that? Do you expect such a staining?
Based on what we know about this protein, we are seeing the expected staining pattern. Please see other instances of nuclear staining at the human protein atlas informational site. I think you may find it useful. Please let me know if you have any additional questions, email@example.com.
I am sure that based on your knowledge you are seeing the expected staining pattern. What concerns me is that the literature on gmf-beta is very poor and it all describes a maturation factor produced in astrocytes and retained in the cytosol. Could you please give me some reference to justify the fact that the signal is not in astrocytes but in neurons?
Here is the information that I received from the lab: We have tested this antibody (Anti-GMFB) in different tissues and have indeed seen some staining of glia cells as well. The image chosen to represent this product shows staining of neurons, and we believe this staining pattern to be accurate and representative based on the comment in UniProt regarding the function for this target: This protein causes differentiation of brain cells, stimulation of neural regeneration, and inhibition of proliferation of tumor cells. (UniProt P60983) Expression of this protein in neurons is also described in the following article; Wang et al. Polyclonal antibody localizes glia maturation factor fl-like immunoreactivity in neurons and glia, Brain Research, 591 (1992) 1-7 (PubMed ID 1446220).
