ELISA Image 1: PathScan® Phospho-DDR1 (panTyr) Sandwich ELISA Kit
Figure 1: Constitutive phosphorylation of DDR1 in Calu-3 cells lysed in the presence of phosphatase inhibitors* (phospho lysate) is detected by PathScan® Phospho-DDR1 (panTyr) Sandwich ELISA Kit #7863 (upper, right). In contrast, a low level of phospho-DDR1 protein is detected in Calu-3 cells lysed in the absence of phosphatase inhibitors* (nonphospho lysate). Similar levels of total DDR1 protein from both nonphospho and phospho lysates are detected by PathScan® Total DDR1 Sandwich ELISA Kit #7845 (upper, left). Absorbance at 450 nm is shown in the top figure while corresponding western blots using a Phospho-DDR1 (Tyr792/796/797) rabbit antibody (right) or a total DDR1 rabbit antibody (left) are shown in the bottom figure. *Phosphatase inhibitors include sodium pyrophosphate, β-glycerophosphate and Na3VO4.

Product Information

Product Description

The PathScan® Phospho-DDR1 (panTyr) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of tyrosine-phosphorylated DDR1 protein. A DDR1 rabbit antibody has been coated on the microwells. After incubation with cell lysates, DDR1 protein (phospho and nonphospho) is captured by the coated antibody. Following extensive washing, a phospho-tyrosine mouse mAb is added to detect captured tyrosine-phosphorylated DDR1 protein. Anti-mouse IgG, HRP-linked antibody is then used to recognize the bound detection antibody. HRP substrate TMB is added to develop color. The magnitude of the absorbance for this developed color is proportional to the quantity of DDR1 protein phosphorylated on tyrosine residues.

*Antibodies in this kit are custom formulations specific to kit.

Protocol

Specificity / Sensitivity

PathScan® Phospho-DDR1 (panTyr) Sandwich ELISA Kit detects endogenous levels of tyrosine-phosphorylated DDR1 protein in human cells, as shown in Figure 1. The kit sensitivity is shown in Figure 2. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Species Reactivity:

Human

Background

The discoidin domain receptors (DDRs) are receptor tyrosine kinases with a discoidin homology repeat in their extracellular domains, activated by binding to extracellular matrix collagens. So far, two mammalian DDRs have been identified: DDR1 and DDR2 (1). They are widely expressed in human tissues and may have roles in smooth muscle cell-mediated collagen remodeling (2). Research studies have implicated aberrant expression and signaling of DDRs in human diseases related to increased matrix degradation and remodeling, such as cardiovascular disease, liver fibrosis, and tumor invasion (1).
