| Molecular Weight | The recombinant mouse REG4 comprises 146 amino acids and has a predicted molecular mass of 17.5 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rm REG4 is approximately 23-30 kDa due to glycosylation. |
| predicted N | Asp 23 |
| SDS-PAGE |  |
| Purity | > 95 % as determined by SDS-PAGE |
| Protein Construction | A DNA sequence encoding mouse REG4 (NP_080604.2) (Met 1-Thr 157) was expressed with the polyhistide tag at the C-terminus. |
| Bio-activity | Measured by the ability of the immobilized protein to support the adhesion and proliferation of HCT-116 human colorectal carcinoma cells (ATCC: CCL-247) under low serum conditions. When 5 x 10E4 cells/well are added to mouse REG4 coated plates (0.16 μg/ml and 100 μl/well), >70% cell will adhere after 60 minutes at 37℃. |
| Research Area | Cancer |Signal transduction |Cytoskeleton / ECM |Cell Adhesion |Lectin |C-tyep lectin | |
| Formulation | Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. |
| Background | Regenerating islet-derived protein 4, also known as REG-like protein, REG4, GISP and RELP, a member of the regenerating gene family belonging to the calcium (C-type) dependent lectin superfamily, has been found to be involved in malignancy in several different organs including the stomach, colorectum, pancreas and prostate. It is highly expressed in the gastrointestinal tract and markedly up-regulated in colon adenocarcinoma, pancreatic cancer, gastric adenocarcinoma, and inflammatory bowel disease. Expression of the Reg4 in different cell types has been associated with regeneration, cell growth and cell survival, cell adhesion and resistance to apoptosis. REG4 protein overexpression is associated with an unfavorable response to preoperative chemoradiotherapy and may be used as a predictive biomarker clinically. REG4 may play an important role in the development and progression of colorectal cancer, as well as in intestinal morphogenesis and epithelium restitution. |
