| Short Description: |
This human PAPPA 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: |
PAPPA |
| Gene ID: |
5069 |
| Uniprot ID: |
PAPP1_HUMAN |
| Specificity: |
This kit recognizes Human PAPPA in samples. No significant cross-reactivity or interference between Human PAPPA and analogues was observed. |
| Sample Type: |
Serum, plasma and other biological fluids |
| Tissue Specificity | High levels in placenta and pregnancy serum. In placenta, expressed in X cells in septa and anchoring villi, and in syncytiotrophoblasts in the chorionic villi. Lower levels are found in a variety of other tissues including kidney, myometrium, endometrium, ovaries, breast, prostate, bone marrow, colon, fibroblasts and osteoblasts. |
| Post Translational Modifications | There appear to be no free sulfhydryl groups. |
| Function | Metalloproteinase which specifically cleaves IGFBP-4 and IGFBP-5, resulting in release of bound IGF. Cleavage of IGFBP-4 is dramatically enhanced by the presence of IGF, whereas cleavage of IGFBP-5 is slightly inhibited by the presence of IGF. |
