This Nkx6.1 antibody is useful for Immunohistochemistry-paraffin embedded sections. In IHC-P, staining was observed in the nucleus of mouse intestines. Prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended.In Simple Western only 10-15 uL of the recommended dilution is used per data point.
NKX6.1 (homeobox protein Nkx-6.1) is a transcription factor that binds to specific A/T-rich sequences in promoter regions of several genes and is known for its involvement in transcriptional regulation in islet beta cells via NKX6.1-insulin promoter binding mediated control of insulin gene. Together with NKX2-2 as well as IRX3, NKX6.1 acts to restrict the generation of motor neurons to the appropriate region of the neural tube. It belongs to neuronal progenitor factors class II proteins that are induced by SHH signals and is a member of the homeodomain family of transcription factors responsible for multiple organ systems development. The pancreatic development involves many such homeodomain proteins including Hb9, Pdx1, Pax4, Nkx2.2, and importantly on Nkx6.1 and mice deficient for Nkx6.1 display a dramatic reduction in beta-cell numbers in pancreas with near-normal development of other glandular cell types. Moreover, Nkx6.1 deficient mice have significant defects involving V2 interneuron and motor neuron specification in the ventral spinal cord, thereby emphasizing an important parallel in developmental pathways leading to beta-cells and neurons.

FAQs for NKX6.1 (2)
In the immunohistochemistry paraffin section protocol....the PBS buffer....should it be at certain pH?
For IHC application, different labs cites the pH of PBS buffer in the range of 7.1 - 7.6 but most commonly used pH is pH 7.4 (this is what we use in our lab). You may use this PBS (pH 7.4) for making permeablization buffer, antibody diluent buffers and for making wash buffer. For more on the protocol that we use in our lab and for IHC-P troubleshooting suggestions, you may visit: IHC-P Protocol and IHC-P Troubleshooting.
I was wondering what does Format 7C mean as far as anitbodies go?
7C is a fluorophore - it is useful for FLOW. The details of the fluor are (A=425, E=500)
