Product overview
Rat Cystatin C ELISA Kit (ab201281) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Cystatin C protein in cell culture supernatant, cit plasma, edta plasma, serum, and tissue extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate Rat Cystatin C with 11.72 pg/ml sensitivity.
SimpleStep ELISA® technology 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. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Notes
Cystatin C, which belongs to the type II cystatin gene family, is a potent inhibitor of lysosomal proteinases. It is expressed in many organs of the body, and is an important extracellular inhibitor of cysteine proteases. As an inhibitor of cysteine proteinases, this protein is thought to serve an important physiological role as a local regulator of this enzyme activity.

Function
As an inhibitor of cysteine proteinases, this protein is thought to serve an important physiological role as a local regulator of this enzyme activity. -
Tissue specificity
Expressed in submandibular and sublingual saliva but not in parotid saliva (at protein level). Expressed in various body fluids, such as the cerebrospinal fluid and plasma. Expressed in highest levels in the epididymis, vas deferens, brain, thymus, and ovary and the lowest in the submandibular gland. -
Involvement in disease
Amyloidosis 6
Macular degeneration, age-related, 11 -
Sequence similarities
Belongs to the cystatin family. -
Post-translational
modificationsThe Thr-25 variant is O-glycosylated with a core 1 or possibly core 8 glycan. The signal peptide of the O-glycosylated Thr-25 variant is cleaved between Ala-20 and Val-21. -
