背景资料This gene is part of a 500 kb inverted duplication on chromosome 5q13. This duplicated region contains at least four genes ａnd repetitive elements which make it prone to rearrangements ａnd deletions. The repetitiveness ａnd complexity of the sequence have also caused difficulty in determining the organization of this genomic region. The telomeric ａnd centromeric copies of this gene are nearly identical ａnd encode the same protein. However, mutations in this gene, the telomeric copy, are associated with spinal muscular atrophy; mutations in the centromeric copy do not lead to disease. The centromeric copy may be a modifier of disease caused by mutation in the telomeric copy. The critical sequence difference between the two genes is a single nucleotide in exon 7, which is thought to be an exon splice enhancer. Note that the nine exons of both the telomeric ａnd centromeric copies are designated historically as exon 1, 2a, 2b, ａnd 3-8. It is thought that gene conversion events may involve the two genes, leading to varying copy numbers of each gene. The protein encoded by this gene localizes to both the cytoplasm ａnd the nucleus. Within the nucleus, the protein localizes to subnuclear bodies called gems which are found near coiled bodies containing high concentrations of small ribonucleoproteins (snRNPs). This protein forms heteromeric complexes with proteins such as SIP1 ａnd GEMIN4, ａnd also interacts with several proteins known to be involved in the biogenesis of snRNPs, such as hnRNP U protein ａnd the small nucleolar RNA binding protein. Multiple transcript variants encoding distinct isoforms have been described.

抗体保存得当与否直接决定了抗体的活性和使用效果。如果抗体保存得当，大部分抗体活性都可以维持数月甚至数年。请按照说明书或者抗体标签上推荐的保存条件正确保存抗体！无论是保存还是运输，绝对避免反复冻融抗体！

1.拿到抗体后请务必在1000-3000转离心1-2分钟后再打开管盖进行分装和保存！（由于运输过程中反复颠簸，管内微量抗体容易聚集在管盖处，一旦直接打开容易流失抗体。请放心抗体出厂时保证已装入足量。）

2.对于大部分抗体，比较合适的保存方式是分装后保存在-20℃冰箱。

◇分装可以程度降低反复冻融对抗体活性的损害，SMN1+SMN2抗体同时也降低了多次从同一管中吸取抗体造成污染的可能性。

◇分装的量以一次实验用完为好，但建议*少不要少于10μL每份。分装体积越小，抗体浓度可能会受到蒸发以及管壁吸附的影响，同时分装次数越多移液吸头吸附的抗体也越多，可能会误认为抗体没有足量装入。（用无菌的进口0.2ML离心管来分装抗体，国产的小管一般没有经过很好的硅化处理，容易吸附抗体蛋白，影响抗体活性。）

◇分装时请将无菌的微量移液器吸头先插入管底部反复吹打几次后再吸出抗体，SMN1+SMN2抗体以便抗体有效成分与抗体保护剂充分混匀。

◇复融后的分装抗体如果一次用不完，请将剩余母液保存在4℃冰箱，避免再冻起来！

◇绝对避免将抗体保存在自动除霜冰箱的冷藏室中。尽量将抗体保存在手动除霜冰箱里面，而不是在冰箱门上。

3.大部分抗体收到后4℃短暂保存1-2周对抗体活性是基本没有影响的。如果抗体很快（1-2周内）就能使用完，推荐在4℃保存，避免反复冻融对抗体活性的损害。如果要长期保存则分装后-20℃保存。

4.即用型抗体请务必保存在4℃冰箱，一定不能冷冻保存。

5.特殊抗体的保存：

◇酶联抗体：一般保存在4℃，尽量避免冷冻起来。否则可能会导致酶活力的下降或者丧失。

◇偶联抗体：所有偶联抗体需要4℃避光保存。尤其是荧光标记抗体，对光极为敏感，因此所有实验阶段也是要避光操作的。
