| Short Description: |
This CTSD Sandwich ELISA is an in-vitro enzyme-linked immunosorbent assay for the measurement of samples in human cell culture supernatant, serum and plasma (EDTA, citrate, heparin). |
| 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: |
Colormetric |
| Gene Symbol: |
CTSD |
| Gene ID: |
1509 |
| Uniprot ID: |
CATD_HUMAN |
| Specificity: |
This kit recognizes Human CTSD in samples. No significant cross-reactivity or interference between Human CTSD and analogues was observed. |
| Sample Type: |
Serum, plasma and other biological fluids |
| Post Translational Modifications | N- and O-glycosylated. Undergoes proteolytic cleavage and activation by ADAM30. As well as the major heavy chain which starts at Leu-169, 2 minor forms starting at Gly-170 and Gly-171 have been identified. An additional form starting at Ala-168 has also been identified. |
| Function | Acid protease active in intracellular protein breakdown. Plays a role in APP processing following cleavage and activation by ADAM30 which leads to APP degradation. Involved in the pathogenesis of several diseases such as breast cancer and possibly Alzheimer disease. |
