| Short Description: |
This human PRG4 kit is a highly sensitive in-vitro chemiluminescent immunoassay for the measurement of trace amounts of analytes. |
| Storage Instruction: |
If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual. |
| Assay Time: |
3.5h |
| Detection: |
Chemiluminescence |
| Gene Symbol: |
PRG4 |
| Gene ID: |
10216 |
| Uniprot ID: |
PRG4_HUMAN |
| Specificity: |
This kit recognizes Human PRG4 in samples. No significant cross-reactivity or interference between Human PRG4 and analogues was observed. |
| Sample Type: |
Serum, plasma and other biological fluids |
| Tissue Specificity | Highly expressed in synovial tissue, cartilage and liver and weakly in heart and lung. Isoform B is expressed in kidney, lung, liver, heart and brain. Isoform C and isoform D are widely expressed. |
| Post Translational Modifications | N-glycosylated. O-glycosylated.contains glycosaminoglycan chondroitin sulfate and keratan sulfate. O-glycosylated with sialylated oligosaccharides which are predominantly represented by the monosialylated core type I structure, NeuNAcalpha2-3Galbeta1-3GalNAc, with smaller amounts of disialylated O-glycans. The disulfide bond between Cys-1146 and Cys-1403 is essential for protein cleavage. Proteolytically cleaved by cathepsin CTSG. |
| Function | Plays a role in boundary lubrication within articulating joints. Prevents protein deposition onto cartilage from synovial fluid by controlling adhesion-dependent synovial growth and inhibiting the adhesion of synovial cells to the cartilage surface. Isoform F plays a role as a growth factor acting on the primitive cells of both hematopoietic and endothelial cell lineages. |
