BP Fluor 532 maleimide 是一种光稳定性、亮黄色荧光染料，pH 值不敏感，发射范围为 pH 4 至 pH 10。BP Fluor 532 的激发非常适合倍频 Nd:YAG 激光线。BP Fluor 532 染料可与多种抗体、肽、蛋白质、示踪剂和扩增底物结合，通常用于在成像和流式细胞术中产生稳定的信号。马来酰亚胺是将染料与蛋白质、寡核苷酸硫代磷酸酯或低分子量配体上的硫醇基团结合的最常用的巯基反应基团。马来酰亚胺基团在 pH 值为 6.5 至 7.5 时与还原硫醇（巯基，-SH）特异性且高效地反应，形成稳定的硫醚键。所得结合物比许多其他光谱相似的荧光团的结合物表现出更亮的荧光和更高的光稳定性。

生物活性

BP Fluor 532 maleimide is a photostable, bright yellow-fluorescent dye with pH insensitive emission from pH 4 to pH 10. The excitation of BP Fluor 532 is ideally suited for the frequency-doubled Nd:YAG laser line. BP Fluor 532 dye can be conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates, and is often used for the generation of stable signals in imaging and flow cytometry. Maleimide is the most popular sulfhydryl-reactive group for conjugating the dye to a thiol group on a protein, oligonucleotide thiophosphate, or low molecular weight ligand. The maleimide group specifically and efficiently reacts with reduced thiols (sulfhydryl groups, –SH) at pH 6.5 to 7.5 to form a stable thioether bond. The resulting conjugates exhibit brighter fluorescence and greater photostability than the conjugates of many other spectrally similar fluorophores.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
