The polyclonal antibody recognizes mouse Spi-6, also known as serpin B9, a cytoplasmic serine protease inhibitor of ~42 kD. Spi-6 is expressed in dendritic cells, lymphocytes and specific cell types at immune-privileged sites. It inactivates granzyme B, a natural occurring inducer of programmed cell death. As such, Spi-6 functions as anti-apoptotic protein. In cytotxic T cells (CTL), Spi-6 is required to protect clonal bursts (expansion) from granzyme B induced cell death. However, it is not required for the development of memory cells. Expression of SPI-6 is of crucial importance in the escape of several tumors from a CTL response and is, therefore, a parameter that influences the feasibility of CTL-mediated immunotherapy of cancer. The polyclonal antibody shows no crossreactivity with mouse proteins related to Spi-6.

Flow cytometry, Immuno assays, Western blot

For flow cytometry and Western blotting, dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:50.

  • New Human Complement Pathway Assays
    We are very proud of our newly developed human classical and alternative complement pathway assays. They are produced in response to a growing demand for quantitative investigation of complement inhibitors or regulators at lower sample dilutions. This development aims to address the issue of false negative results, enabling more accurate and reliable analysis of complement… Read more: New Human Complement Pathway Assays
  • Navigating the pitfalls in complement analysis
    Our colleague Erik Toonen shared his experience on how to analyze complement at the Complement-based Drug Development Summit in Boston in September 11-13th, 2023. He showed valuable insights on analyzing complements. For accurate complement analysis, it is important that not only the correct technique is used but also that pre-analytical sample handling is performed in… Read more: Navigating the pitfalls in complement analysis
  • NEW Human C3d ELISA
    We are happy to introduce our new ELISA (cat.# HK3017) designed to detect human C3d. What sets this assay apart is its utilization of a distinctive neo-epitope capture antibody that selectively targets a specific C3d region of the alpha chain, which is not available in other C3 variants. This way it specifically distinguishes C3d from native C3… Read more: NEW Human C3d ELISA
