GFP标签是一类绿色荧光蛋白标签，其融合目的蛋白可自发荧光，广泛应用于目的基因在细胞中的定位，可应用于检测基因表达效率以及目的蛋白的表达和分布。Y-Tec GFP beads(human)是将抗GFP人源化重组单克隆抗体共价偶联到4%琼脂糖珠上，用于捕获哺乳动物、植物、细菌、酵母、昆虫等多种生物的细胞提取物中的含GFP标签的蛋白及与其紧密相互作用的蛋白，可用于 GFP(EGFP或其变体)标签融合蛋白的免疫沉淀（IP），chIP实验与蛋白纯化。

This gene encodes a member of the glyceraldehyde-3-phosphate dehydrogenase protein family. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions.

This gene encodes one of six different actin proteins. Actins are highly conserved proteins that are involved in cell motility, structure, and integrity. This actin is a major constituent of the contractile apparatus and one of the two nonmuscle cytoskeletal actins.

The DYKDDDDK peptide has been used extensively as a general epitope tag in expression vectors. This peptide can be expressed and detected with the protein of interest as an amino-terminal or carboxy-terminal fusion.

Epitope tags are useful for the labeling and detection of proteins using immunoblotting,immunoprecipitation, and immunostaining techniques. Because of their small size, they are unlikely to affect the tagged protein’s biochemical properties.
