Influenza NP (311-325) 是一种有生物活性的肽。(该肽是流感病毒核蛋白 (NP) 的氨基酸 311 至 325 片段。这种来自流感病毒的真正的 MHC II 类限制性表位被用来研究感染期间的宿主免疫反应。在细胞内细胞因子测定中，该肽可引发最强的γ干扰素 (IFN-γ) 产生。它不会刺激小鼠的 CD8 T 细胞。当谷氨酰胺 (Q) 或谷氨酸 (E) 位于序列 N 末端时，焦谷氨酰 (pGlu) 肽可能会自发形成。 Q或E向pGlu的转化是自然发生的，并且一般认为pGlu的疏水性γ-内酰胺环可能在针对胃肠道蛋白酶的肽稳定性中发挥作用。因此，焦谷氨酰肽被认为是此类肽的正常子集，并在 HPLC 分析期间作为肽纯度的一部分包含在内。)

生物活性

Influenza NP (311-325) is a biological active peptide. (This peptide is amino acids 311 to 325 fragment of the influenza virus nucleoprotein (NP). This bona fide MHC class II restricted epitope from influenza virus was used to study the host immunoresponse during the infection. This peptide elicits the strongest gamma interferon (IFN-gamma) production in the intracellular cytokine assays. It does not stimulate CD8 T-cells in mice.Pyroglutamyl (pGlu) peptides may spontaneously form when either Glutamine (Q) or Glutamic acid (E) is located at the sequence N-terminus. The conversion of Q or E to pGlu is a natural occurrence and in general it is believed that the hydrophobic γ-lactam ring of pGlu may play a role in peptide stability against gastrointestinal proteases. Pyroglutamyl peptides are therefore considered a normal subset of such peptides and are included as part of the peptide purity during HPLC analysis.)

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.
