2. Please refer to us for technical protocols.
3. Alexa Fluor is a registered trademark of Molecular Probes, Inc., Eugene, OR.
4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
5. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
Purification Purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name SMN
Background SMN (survival motor neuron) was discovered as a candidate gene, located in chromosome 5q13, for the fatal autosomal Spinal muscular atrophy (SMA) disorder. The SMN gene was missing or interrupted in a significant number of patients with SMA. The SMN protein is 294 amino acids and migrates with apparent molecular weight of 40 kDa. In addition to the cytoplasm, other studies localized SMN in dots of 0.1-1.0 µm within the nucleus. These novel nuclear structures were named gems and found associated to coiled bodies. It was also found that SMN interacts with the RGG box of hnRNP U and fibrillarin. Therefore, the biochemical function of SMN may be in the regulation of mRNA metabolism.
Synonyms: Survival Motor Neuron

anti-Small Nuclear Ribonucleoprotein N (SNRPN) (AA 14-174) antibody (2) Immunohistochemical staining of pyrimidal cells in a rat cortex, formalin-fixed paraffin-embedded tissue section, with citrate pre-treatment (magnification, 20X) (center).
anti-Small Nuclear Ribonucleoprotein N (SNRPN) (AA 14-174) antibody (3) Immunofluorescent staining of differentiated SH-SY5Y cells (right). Cells were seeded in a 96 well, collagen coated imaging plate at ~ 5,000 cells per well. Cells were incubated with 50 M ATRA for 5 days, followed by 50 ng/ml BDNF for 5 days. Differentiated cells were fixed and stained using the Triton X100 fix/perm protocol (see Recommended Assay Procedure, Bioimaging protocol link) and the anti-SMN antibody. The second step reagent was Alexa Fluor® 488 goat anti mouse Ig (Invitrogen)(pseudo colored green). Cell nuclei were counter stained with Hoechst 33342 (pseudo colored blue). The image was taken using a 20x objective and merged using the BD AttoVison ™ software This antibody also stained undifferentiated SH-SY5Y, SK-N-SH, C6, U87 and U373 cells using both the Triton X100 and methanol fix/perm protocols (see Recommended Assay Procedure, Bioimaging protocol link).
