Sandwich ELISA - Human Cytokeratin 18 Fragment ELISA Kit (CK18-30) (AB254515)
Interpolated concentrations of native Cytokeratin 18 Fragment (CK18-30) in human HeLa cell extract and extract based on a 12.5 μg/mL and 1.56 µg/mL extract load (respectively).
The concentrations of Cytokeratin 18 Fragment were measured in duplicate and interpolated from the Cytokeratin 18 Fragment standard curve and corrected for sample dilution and extract load. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Cytokeratin 18 Fragment concentration was determined to be 42.1 pg/mL / μg/mL in untreated and 394 pg/mL / μg/mL in STS treated HeLa cell extract.

Sandwich ELISA - Human Cytokeratin 18 Fragment ELISA Kit (CK18-30) (AB254515)
Interpolated concentrations of native Cytokeratin 18 Fragment (CK18-30) in human HeLa cell culture supernatant samples.
The concentrations of Cytokeratin 18 Fragment were measured in duplicates, interpolated from the Cytokeratin 18 Fragment standard curves and corrected for sample dilution. Undiluted samples are as follows : untreated 100% and staurosporine treated (4hr at 1 μM) 100%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Cytokeratin 18 Fragment concentration was determined to be 239 pg/mL in untreated and 400 pg/mL in STS treated cell culture supernatant.

제품 세부 정보
Human Cytokeratin 18 Fragment ELISA Kit (CK18-30) ab254515 is a rapid single-wash 90-min Sandwich ELISA to measure Human Cytokeratin 18 Fragment (CK18-30)in cell culture supernatant, cell lysate, citrate plasma, EDTA plasma, heparin plasma, serum. This SimpleStep sensitivity is 22.8 pg/mL.
How the assay works
Human Cytokeratin 18 Fragment (CK18-30)SimpleStep ELISA®employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA® kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.
Human Cytokeratin 18 Fragment ELISA Kit (CK18-30) ab254515 protocol summary
1. Mix: add samples/standards to the wells together with the capture and detector antibody cocktail. Incubate 1 hr at room temperature
2. Wash
3. Add TMB development solution - incubate for 10 min
4. Add Stop solution
5. Read the results on a plate reader at 450 nm
Cytokeratin 18 Fragment is a degradation product of Cytokeratin 18. Cytokeratin 18 is involved in the uptake of thrombin-antithrombin complexes by hepatic cells. Cytokeratin 18 becomes cleaved during apoptosis resulting in a 18kDa fragment, which can be used as a measure of cell death and a biomarker for liver disease. ab254515 recognizes this fragment, and specifically recognizes the cleavage site (M30) neo-epitope and does not recognize the full-length protein.

Biological function summary
CK18 maintains cellular integrity and mediates resistance to mechanical and non-mechanical stresses in epithelial cells. It forms heterodimers with KRT8 participating in a complex network of filaments important for maintaining cell shape and stability. This organization plays a role in managing cell survival during stress and apoptosis helping regulate cellular functions and responses in tissues where it is expressed.
Pathways
Cytokeratin 18 is involved in the apoptosis and cellular stress response pathways. It interacts with proteins such as caspases during apoptosis facilitating cytoskeletal reorganization and cell fragmentation. CK18 in coordination with KRT8 also participates in signaling pathways that regulate cell cycle and apoptotic processes underlining its importance in cellular turnover and tissue homeostasis.
