Protocols

Specificity / Sensitivity

14-3-3 η (D23B7) Rabbit mAb recognizes endogenous levels of total 14-3-3 η. This antibody shows weak cross-reactivity with 14-3-3 γ but does not detect any other 14-3-3 family isoforms.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu37 of human 14-3-3 η protein.

Western Blotting

Western Blotting

Western blot analysis of whole cell extracts from various cell lines using 14-3-3 η (D23B7) Rabbit mAb.

Isoform Specificity

Isoform Specificity

Isoform specificity of 14-3-3 η (D23B7) Rabbit mAb. Recombinant, purified, GST-tagged 14-3-3 protein isofoms (2 µg each) were resolved by SDS-PAGE, transferred to nitrocellulose and blotted with either 14-3-3 η (D23B7) Rabbit mAb (upper) or GST (91G1) Rabbit mAb #2625 (lower).

Background

Plasminogen is a zymogen that produced mainly by liver and circulates in blood (1, 2). Its structure has a 77 aa N-terminal activation peptide, followed by 5 kringle domains and a serin-proteinase domain. Plasminogen system play important role in dissolving the fibrin of blood clots and promoting cell migration by proteolytic degradation of extracellular matrix proteins and activation of MMPs(2,3). Plasminogen is activated through two steps, binding to the cell surface through interaction with its receptors and subsequent releasing of active serine proteinase from zymogen cleavage by acitvator t-PA (Tissue specific plasminogen activator) or u-PA (Urokinase plasminogen activator) (2,3). There are many plasminogen receptor identified on the cell surface, such as S100A10, enolase and PLG-R(KT) (4-6), etc. These receptors all has lysine residues at their C-terminal to interact with the kringle domain of plasminogen, leading to plasminogen localization on cell surface. Once on cell surface, the receptors also interact with t-PA/u-PA, presenting surface bound plasminogen for cleavage into active plasmin (2,3,7). Plasminogen system play importance role in biological process such as tumor migration and invasion, wound healing, macrophage recruitment, and srem cell mobilization (8-14).
