Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro171 of human CYR61 protein.

Background

Cysteine-rich protein 61 (CYR61, CCN1) is a secreted, matrix-associated protein belonging to the CCN family, a protein group characterized primarily by its high cysteine content (1). CYR61 regulates diverse cellular events including cell proliferation, differentiation, angiogenesis, and extracellular matrix formation. Research studies have implicated CYR61 in the development or progression of various cancers, including breast, prostate, lung, and hepatocellular carcinoma (1-4). Notably, its role in promoting cancer progression appears to be context-dependent. For example, investigators have shown that overexpression of CYR61 was positively associated with invasiveness of breast cancer cell lines (2), whereas in primary prostate tumors, expression levels were inversely correlated with tumor aggressiveness (3). In additional research studies of hepatocellular carcinoma, where CYR61 expression was positively associated with cancer progression, CYR61 was shown to be transcriptionally regulated by the Wnt/β-catenin signaling pathway (1).

CYR61 (D4H5D) XP® Rabbit mAb

Western Blotting Image 1: CYR61 (D4H5D) XP® Rabbit mAb Expand Image
Western blot analysis of extracts from various cell lines using CYR61 (D4H5D) XP® Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower). As expected, MCF7 cells are negative for CYR61 expression.
Immunofluorescence Image 1: CYR61 (D4H5D) XP® Rabbit mAb Expand Image
Confocal immunofluorescent analysis of Saos-2 cells, untreated (left) or treated with Brefeldin A #9972 (10 μg/ml, overnight; center), and untreated MCF7 cells (right), using CYR61 (D4H5D) XP® Rabbit mAb (green). Actin filaments were labeled with DyLight 554 Phalloidin #13054 (red). Blue pseudocolor = DRAQ5® #4804 (fluorescent DNA dye).
Flow Cytometry Image 1: CYR61 (D4H5D) XP® Rabbit mAb Expand Image
Flow cytometric analysis of 293T cells (blue) and PANC-1 cells (green) using CYR61 (D4H5D) XP® Rabbit mAb (solid lines) or a concentration-matched Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 (dashed lines). Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 488 Conjugate) #4412 was used as a secondary antibody.
