Expression of GluR1 in mouse hippocampusImmunohistochemical staining of mouse hippocampus with Anti-GluR1 (GluA1) (extracellular) Antibody (#AGC-004). GluR1 (green) is present in the stratum oriens (Or) and radiatum (Ra) but not in the pyramidal layer (P). Staining of the same section with mouse anti-parvalbumin (red) identifies the pyramidal layer.

AMPA receptors are members of the glutamate receptor family of ion channels that also include the NMDA and Kainate receptors. The three subfamilies are named after the original synthetic agonists that were identified as selective ligands of each family.
The α-amino-3-hydroxy-5-methyl-4-isoazolepropionic acid (AMPA) receptor subfamily includes four members AMPA1-AMPA4 that are also known as GluR1-GluR4 respectively.
The functional AMPA channel is believed to be a tetramer, with most neuronal AMPA receptors being actually heterotetramers composed of AMPA1 plus AMPA2 or AMPA2 plus AMPA3, although homotetramers can also be found.
AMPA receptors are permeable to cations Na+, K+ and Ca2+. The Ca2+ permeability is dependent on the presence of AMPA2: whenever this subunit is present, the channel will be impermeable to Ca2+. The Ca2+ permeability of the AMPA2 subunit is determined by the presence of an arginine (R) at a critical site in the pore loop instead of a glutamine (Q) present in the same site in the other AMPA subunits. A post-transcriptional process known as RNA editing determines the presence of this R. Since most AMPA2 subunits in the adult brain have undergone RNA editing and most AMPA receptors contain the AMPA2 subunit, most native AMPA receptors will be impermeable to Ca2+.
Gating of AMPA receptors by glutamate is extremely fast and therefore the AMPA receptors mediate most excitatory (depolarizing) currents in the brain during basal neuronal activity. The depolarization caused by the activation of post-synaptic AMPA receptors is necessary for the activation of NMDA receptors that will open only in the presence of both glutamate and a depolarized membrane.
Synaptic strength, defined as the level of post-synaptic depolarization, can be long term (hence the term long term potentiation, LTP) and therefore induce changes in signaling and protein synthesis in the activated neuron. These changes are associated with memory formation and learning.
Changes in synaptic strength are thought to involve rapid movement of the AMPA receptors in and out of the synapses and a great deal of effort has focused in understanding the mechanisms that govern AMPA receptor trafficking.
Anti-GluR1 (GluA1) (extracellular) Antibody (#AGC-004) is a highly specific antibody directed against an extracellular epitope of the rat ionotropic glutamate receptor 1. The antibody can be used in western blot, immunohistochemistry, immunocytochemistry, and live cell imaging applications. It has been designed to recognize GluR1 from human, mouse, and rat samples.

抗体指机体的免疫系统在抗原刺激下,由B淋巴细胞分化成的浆细胞所产生的、可与相应抗原发生特异性结合反应的免疫球蛋白.
载体,你说的是那种载体?生命科学载体有2种,一种是分布于膜上的载体蛋白,和物质运输有关.另一种是基因工程里面的携带外源DNA的一段DNA片段,例如质粒、噬菌体和动植物病毒.
所以,抗体全部是蛋白质,载体部分是蛋白质.
根据这个信息进行适宜的选择。
