The green fluorescent protein (GFP) is a protein that exhibit bright green fluorescence when exposed to blue light. GFPSparkTM is an improved variant of the green fluorescent protein GFP. It possesses bright green fluorescence (excitation/ emission max = 487 / 508 nm) that is visible earlier than fluorescence of other green fluorescent proteins. GFPSparkTM is mainly intended for applications where fast appearance of bright fluorescence is crucial. Its amazing ability to generate a highly visible, efficiently emitting internal fluorophore is both intrinsically fascinating and tremendously valuable. It is specially recommended for cell and organelle abeling and tracking the promoter activity.

文献和实验dmdfe 本人将GFP基因后面加了一段大约110bp的序列，插入PET28A的BamH1和Hind3位点，最后在BL21中表达。 经SDS-PAGE验证表明： 目的蛋白 大量存在菌体裂解后沉淀即包涵体中，但是该沉淀无色。 少量存在于上清中，上清显微弱的绿色。 看文献大量报道GFP融合蛋白几乎都形成可溶性表达，目的蛋白在上清中，并且诱导条件没有太大要求。 想请教一下各位做过GFP原核表达的经验
dingxiangyua 有哪位高手知道F-GFP和GFP-actin的抗性分别是什么?急求 Fasta921 定位在膜上的GFP （F-GFP） 绿荧光蛋白(GFP)标记肌动蛋白(GFP-Actin) 抗性？不明白！ biyuntian478 lz是啥意思？ 本文由丁香园论坛提供，想了解更多有用的、有意思的前沿资讯以及酷炫的实验
【共享】如何检测GFP、GFP、YFP、EYFP、CFP抗体？
检测GFP、EGFP、YFP、EYFP、CFP的GFP抗体GFP是绿色萤光蛋白（Green Fluorescent Protein）的简称，由238个氨基酸残基组成。GFP蛋白质最早是由下村脩等人在1962年在一种学名Aequorea victoria的水母中发现。其基因所产生的蛋白质，在蓝色波长范围的光线激发下，会发出绿色萤光。GFP或其突变体EGFP标签系统等被广泛用于基因表达效率的检测，以及和目的蛋白融合表达用于检测目的蛋白的表达和分布。我们都知道GFP抗体能应用于GFP的表达检测、纯化
