Immunocytochemistry/ Immunofluorescence: SMN Antibody (2B1) [NB100-1936] - CWC22 is colocalized with nuclear speckles & upregulated in diabetic DRG sensory neurons. (A) Subcellular distribution of TDP-43 & CWC22 in control DRG sensory neurons. TDP-43 was stained diffusely in the nucleus, excluding SMN foci in sensory neurons. CWC22 consistently colocalized with a marker protein SC35 of nuclear speckles in sensory neurons. No obvious differences in the subcellular localization of CWC22 were identified in diabetic neurons (not shown) compared with controls. Scale bar: 10 μm. (B) qRT-PCR analysis of Cwc22 mRNA expression in diabetic & control mice. Cwc22 expression was upregulated ∼2.5-fold in diabetic DRGs. *P<0.05, unpaired two-tailed Student's t-test. Data represented as mean±s.e.m. See Cheng et al. (2015) for microarray data indicating rises in Cwc22 expression as reported separately.

Background: SMN

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 (2B1) - BSA Free

Showing  1 - 1 of 1 FAQ Showing All
  • Q: Could you recommond the Human specific SMN antibody? It will only recognize human SMN, without cross reaction with mouse smn.

    A: 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.
