纯化的抗体可通过不同的途径获取，有些神经生长相关蛋白43可通过下述方法制备或从商家购买。从商家购买的抗体，通常附有正确的储存方法。

1）工作液应在4℃下融化并存放，可能稳定达数月。

2）如果没有特殊原因而避免使用叠氮钠，亦可加入叠氮钠，浓度为0．02％。将纯化的抗体样本分装成合适的体积，于-20℃保存。

3）纯化的抗体溶液应以较高的浓度(如lmg／m1)在中性pH下保存。：常用的抗体储存浓度高达l0mg/ml。较低浓度的抗体冻存前应浓缩。所有标准的浓缩方法(如超滤法)，皆可使用。还有一个简单的方法是用蛋白A或蛋白G亲和柱来浓缩溶液。如果纯化的抗体不是用于标记，可将它们以较低浓度储存于加有1％BSA的溶液中。

4）经纯化制备的抗体在常用的缓冲液中是稳定的。其DH应保持在中性左右。如果pH在7-8之间，即使保存多年，对抗体也无损害。多数情况下，盐浓度适于保持在0-150mmol/L之间，但在长期存放的抗体中，盐溶液浓度高达500mmol/L时，对神经生长相关蛋白43能有损害。如果没有其他说明．律议用PBS或50mmol/LTris(DH8．0)溶液长期存放抗体。

神经生长相关蛋白43产品介绍 Neuronal Marker

GAP-43, a common marker of differentiating neurons, is expressed at elevated levels by developing or regenerating neurons during axon growth. While GAP-43 is an integral membrane protein associated with the cytoplasmic surface of axonal growth cones (and synapses), it is absent from dendritic growth cones. In adult brain, GAP-43 is found in high concentration in presynaptic areas where memory formation is thought to occur, such as frontal cortex, limbic system and hippocampus. Phosphorylation of GAP-43 by PKC (at Ser41 on human, mouse, rat, and bovine GAP-43 or Ser42 on chicken and Xenopus GAP-43) is specifically correlated with certain forms of synaptic plasticity.

Function : This protein is associated with nerve growth. It is a major component of the motile 'growth cones' that form the tips of elongating axons. Plays a role in axonal and dendritic filopodia induction.

Subunit : Identified in a complex containing FGFR4, NCAM1, CDH2, PLCG1, FRS2, SRC, SHC1, GAP43 and CTTN. Binds calmodulin with a greater affinity in the absence of Ca(2+) than in its presence.

Subcellular Location : Cell membrane; Peripheral membrane protein; Cytoplasmic side. Cell projection, growth cone membrane; Peripheral membrane protein; Cytoplasmic side. Cell junction, synapse. Cell projection, filopodium membrane; Peripheral membrane protein. Note=Cytoplasmic surface of growth cone and synaptic plasma membranes.

Post-translational modifications : Phosphorylated at Ser-41 by PHK. Phosphorylation of this protein by a protein kinase C is specifically correlated with certain forms of synaptic plasticity. 

Palmitoylation by ARF6 is essential for plasma membrane association and axonal and dendritic filopodia induction. Deacylated by LYPLA2.

Similarity : Belongs to the neuromodulin family.

Contains 1 IQ domain.

Database links : UniProtKB/Swiss-Prot: P17677.1

神经生物学相关蛋白（Neurobiology）；神经标志物 

GAP43 （Growth associated protein-43）又称作neuromodulin，是一个轴突膜蛋白，是一种神经特异性的蛋白质，参与神经细胞外生长及突触发育形成和神经细胞再生。在神经元发育和再生过程中以高水平表达。能调解轴突延伸作用，改变细胞形态。作为细胞内信号，可大大增强与G蛋白偶联的受体转运作用。

神经生长相关蛋白-GAP-43和神经细胞黏附因子(neural cell adhesion molecule,NCAM)与突触可塑性密切相关.GAP-43是一种神经细胞膜上的特异性磷蛋白,在神经发育和再生过程中呈现高表达,被作为突触生长的标志物,有称脊髓生长相关蛋白

GAP-43与CaM结合,参与G蛋白相互作用,神经递质的释放,作用于胞吞/胞吐过程,通过小囊溶合或诱导生长锥和突触前末端的胞吞促进膜扩展,与海马长时程增强密切相关.

神经细胞黏附因子是细胞表面糖蛋白大家族的成员之一,促进轴突生长,对长时记忆的保持有重要影响,同时,GAP-43对其具调节作用，广泛而深入地研究GAP-43意义深远。
