Product Specifications

Immunogen

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)

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.

Specificity

This affinity-purified antibody is directed against human SerpinB2 protein. Reactivity occurs against human SerpinB2 protein.

Clonality

Polyclonal

Host

Rabbit

Isotype

IgG

Description

This affinity-purified antibody is directed against human PAI-2 protein. The product was affinity purified from monospecific antiserum by immunoaffinity purification

Store vial at -20C prior to opening. Aliquot contents and freeze at -20C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4C as an undiluted liquid. Dilute only prior to immediate use.

Scientific Data Images for SerpinB2 Antibody

Western Blot: SerpinB2 Antibody [NBP1-77964]

Western Blot: SerpinB2 Antibody [NBP1-77964]

Western Blot: SerpinB2 Antibody [NBP1-77964] - 2 in 50 ug of HeLa whole cell lysates. The band at ~42 kDa (arrowhead) corresponds to SerpinB2 . Faint non-specific bands are also noted at lower and higher molecular weights positions. Primary antibody was used at a 1:500 dilution in 5% BLOTTO in PBS reacted overnight at 4C. The membrane was washed and reacted with a 1:5,000 dilution of HRP- conjugated Gt-a-Rabbit IgG for 45 min at room temperature with ECL used for detection. Molecular weight estimation was made by comparison to prestained MW markers.
Immunohistochemistry: SerpinB2 Antibody [NBP1-77964]

Immunohistochemistry: SerpinB2 Antibody [NBP1-77964]

Immunohistochemistry: SerpinB2 Antibody [NBP1-77964] - Tissue: heart. Fixation: formalin fixed paraffin embedded. Primary antibody: Anti-Plasminogen Activator 2 at 10 ug/mL for 1 h at RT. Staining: Plasminogen Activator II as precipitated red signal with hematoxylin purple nuclear counterstain.

Background: Serpin B2

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.
