  • Function

    May act as a protease inhibitor to modulate the host immune response against tumor cells.
  • Tissue specificity

    Squamous cells. Expressed in some hepatocellular carcinoma (at protein level).
  • Sequence similarities

    Belongs to the serpin family. Ov-serpin subfamily.
  • Developmental stage

    Its expression is closely related to cellular differentiation in both normal and malignant squamous cells.
  • Cellular localization

    Cytoplasm. Seems to also be secreted in plasma by cancerous cells but at a low level.

Customer reviews and Q&As


Thank you for contacting us.

I can confirm that although we have not tested these antibodies for cross-reactivity with Serpin B4 but there is high percentage of immunogen sequence homology. It means the chances of cross reactivity are high.

I hope this information is nevertheless helpful to you. Please do not hesitate to contact us if you need any more advice or information.
