Application

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Enzyme-linked immunosorbent assay (1 paper)
Mouse monoclonal clone 2B1 anti-SMN antibody is an important tool for studying the role of the survival of motor neurons protein in nuclear processes and spinal muscular atrophy (SMA). It may be used in immunoblotting (~35 kDa), immunoprecipitation, and immunocytochemistry.

Biochem/physiol Actions

Survival of Motor Neurons (SMN) complex is important in various biological processes, such as assembly and restructuring of spliceosomal small nuclear ribonucleoproteins (snRNPs), pre mRNA splicing and transcription. Spinal muscular atrophy (SMA) is caused by reduced expression or mutations in the survival of motor neurons (SMN) protein. Deletion or mutation in the telomeric copy (SMN1) causes the SMA phenotype. The severity of SMA is in direct correlation with the expression level of the SMN protein, either from the SMN1 gene or a different spliced form of SMN from the SMN2 gene. The SMN complex interacts with various protein substrates such as Sm and Lsm proteins of the spliceosomal snRNPs, fibrillarin, GAR1, RNA helicase A, the human hnRNP proteins (hnRNPQ, U and R), coilin and p53.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in "frostfree" freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.

Genetic defects leading to the reduction of the survival motor neuron protein (SMN) are a causal factor for Spinal Muscular Atrophy (SMA). While there are a number of therapies under evaluation as potential treatments for SMA, there is a critical

The universal presence of a gene (SMN2) nearly identical to the mutated SMN1 gene responsible for Spinal Muscular Atrophy (SMA) has proved an enticing incentive to therapeutics development. Early disappointments from putative SMN-enhancing agent clinical trials have increased interest in
