产品介绍 Elongation factor 1 alpha 2 (EF-1 alpha2) is a eukaryotic protein translation factor that is expressed in terminally differentiated cells of skeletal muscle, heart, and certain areas of the brain. Along with protein synthesis, EF-1 alpha2 also plays a role in cytoskeletal remodelling and apoptosis. The gene encoding for EF-1 alpha2 maps to chromosome 20q13. Wasted (wst) refers to a spontaneous autosomal recessive mutation in which this gene is deleted, and it leads to tremors and disturbances of gait shortly after weaning, followed by motor neuron degeneration, paralysis, and death by about 28 days in mice. EF-1 alpha2 has the ability to transform mammalian cells and is highly expressed in tumors of the ovary, breast, and lung, thereby proving a good candidate for an oncogene. In addition to this, EF-1 alpha2 enhances focus formation, allows anchorage-independent growth, and decreases the doubling time of rodent fibroblasts.
Function : This protein promotes the GTP-dependent binding of aminoacyl-tRNA to the A-site of ribosomes during protein biosynthesis.
Subunit : Monomer
Subcellular Location : Nucleus.
Tissue Specificity : Brain, heart, and skeletal muscle.
Similarity : Belongs to the GTP-binding elongation factor family. EF-Tu/EF-1A subfamily.
Database links : UniProtKB/Swiss-Prot: Q05639.1
半个多世纪以来,抗体一直作为常用的研究工具,因此对其使用和储存已有丰富的经验。这些经验让人们知道如何对抗体进行操作,由于抗体的稳定性好,使用并不困难。抗体较其他蛋白不易变性,易于存放、纯化和标记。蛋白G和蛋白A等抗体结合蛋白的发现使得这项工作更具可行性。
选择合适的抗体对免疫化学技术的成功极为重要。没有任何一种来源的抗体能够满足本书所述的各种方法的要求。为了研究某一重要的抗原,应选用具有不同特性的多种抗体。在没有一套良好特性的抗体可用于研究机体中每一种蛋白之前,选择及制备适合各种技术要求的抗体非常必要。
