Background
Spinal muscular atrophy (SMA) is a common fatal autosomal recessive disorder characterized by the degeneration of motor neurons and muscular atrophy. A gene called Survival of Motor Neurons (SMN) has been identified as the determining gene in SMA and is deleted or mutated in greater than 98% of SMA patients. The SMN protein localizes to both the cytoplasm and the nucleus. In the nucleus, SMN has been found to localize in a nuclear structure termed gems for Gemini of coiled bodies, which contain high levels of small ribonucleoproteins (snRNPs). SMN forms complexes with proteins including SIP1, Gemin 2-7 and several others known to be involved in the biogenesis of snRNPs. SMN antibodies may serve as a useful research tool to study SMN complexes and gems, and their role in pre-RNA processing and RNA metabolism.

FAQs for SMN Antibody (NB100-1936). (Showing 1 - 1 of 1 FAQs).
Could you recommond the Human specific SMN antibody? It will only recognize human SMN, without cross reaction with mouse smn.
We do not have an SMN antibody that has been validated NOT to work in mouse samples. When an antibody is found to not react with a certain species, we mark the data sheet with a (-) next to the species' name. Unfortunately, the SMN antibodies that do not list mouse have not been tested in mouse, and may react.
The concentration calculator allows you to quickly calculate the volume, mass or concentration of your vial. Simply enter your mass, volume, or concentration values for your reagent and the calculator will determine the rest.
