SerpinB2 Antibody Summary

This affinity purified SerpinB2 Antibody was prepared from whole rabbit serum produced by repeated immunizations with a peptide corresponding to an internal area of human SerpinB2 protein. (Uniprot: P05120)
This affinity-purified antibody is directed against human SerpinB2 protein. Reactivity occurs against human SerpinB2 protein.
Immunogen affinity purified
Innovator's Reward
Test in a species/application not listed above to receive a full credit towards a future purchase.


  • ELISA 1:100000-150000
  • Immunohistochemistry 10ug/ml
  • Western Blot 1:500-1:2000
Application Notes
Specific conditions for reactivity should be optimized by the end user. Expect a band 42-46.6 kDa in size corresponding to SerpinB2 protein by western blotting in the appropriate cell lysate or extract.
Theoretical MW
46.6 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Reactivity Notes

A BLAST analysis was used to suggest cross reactivity with SerpinB2 proteins from several primates based on 94% homology with the immunizing sequence. Reactivity against homologues from other sources is not known

Extracellular plasminogen activator inhibitor type-2 (also known as PAI-2, Placental plasminogen activator inhibitor; Monocyte Arg-serpin; Urokinase inhibitor; SERPINB2 serpin peptidase inhibitor, clade B (ovalbumin), member 2) is a coagulation factor and a potent inhibitor of urokinase-type plasminogen activator (u-PA) and also acts as a multifunctional protein. It is present in most cells, especially monocytes and macrophages. PAI-2 exists in two forms, a 60-kDa, secreted, extracellular, glycosylated form and a 43-kDa intracellular form. It is a multifunctional protein that plays a role in cell differentiation, in prevention of programmed cell death, in the regulation of cell proliferation, in the inhibition of microbial proteinases and in the protection against stromal degradation. High levels of the PAI-2 protein are associated with a good prognosis in breast cancer, small cell lung, ovarian cancer, and inhibition of metastasis. PAI-2 also plays a role in inflammation on the surface of the eye. PAI-2 may cooperate with pRb2/p130 in modulating PAI-2 gene expression by chromatin remodeling.
