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。
