제품 세부 정보

Human Cystatin-B is a matched pair of unconjugated recombinant rabbit monoclonal capture and detection antibodies used to quantify Human Cystatin-B in sandwich ELISAs and many other pair-based applications.

Patented technology
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

The pair can be used in variety of assays and platforms including but not limited to:

  • Sandwich ELISA
  • FRET/TR-FRET/HTRF
  • Meso Scale Discovery® (MSD®)
  • Bead-based assays
  • AlphaLISA®/AlphaScreen®
  • DELFIA® immunoassays
  • Simoa® and Single Molecule Counting (SMC™) immunoassays
  • Multiplex

Our antibody pairs are supplied in a carrier-free format that is conjugation-ready:

  • Buffer free of BSA, sodium azide, and glycerol for higher conjugation efficiency.
  • Concentration of ~1 mg/ml as measured by the protein A280 method.

We can label antibodies for you: get in touch today to discuss how we can help accelerate your assay development with custom conjugation services.

Pairs are screened in biological samples, including plasma and serum, to ensure specificity in complex samples.

Please note:

The recommended antibody orientation is based on internal optimization in sandwich ELISA. Antibody orientation is assay dependent and needs to be optimized for each assay type.

The range provided for this antibody pair is based on initial sandwich ELISA validation data using recombinant protein. Performance and range of the antibody pair will depend on the specific characteristics of your assay, including standard protein selection.

We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibodies in other assays.

Antibody properties:

Capture antibody: recombinant rabbit monoclonal (unconjugated) – 100 µg

Detector antibody: recombinant rabbit monoclonal (unconjugated) - 100 µg

Concentration: ~1 mg/ml

Storage buffer: 100% PBS

Form: Liquid

Isotype: IgG

Recombinant monoclonal antibodies offer several advantages including:

- High batch-to-batch consistency and reproducibility

- Improved sensitivity and specificity

- Long-term security of supply

- Animal-free production

추가 정보

This supplementary information is collated from multiple sources and compiled automatically.

Cystatin-B also known as STEFIN-B is a protease inhibitor with a molecular mass of approximately 11 kilodaltons. It belongs to the family of cystatins which are expressed widely in human tissues with notable presence in the brain liver and kidneys. Cystatin-B acts by inhibiting cysteine proteases preventing them from degrading proteins indiscriminately. The inhibition is important for maintaining cellular protein balance and integrity.
Biological function summary

Cysteine protease inhibition by Cystatin-B protects cells from uncontrolled proteolysis which can lead to tissue damage. This protein plays an important role in the regulation of various cellular processes including apoptosis phagocytosis and the response to oxidative stress. It does not form part of a larger complex but interacts directly with its target proteases to exert its inhibitory effects.

Pathways

Cystatin-B influences proteolytic pathways by modulating the activity of cysteine proteases such as cathepsins. By inhibiting these enzymes Cystatin-B participates in the regulation of the lysosomal degradation pathway and apoptotic pathways which are important for cellular turnover and programmed cell death. Cathepsins particularly cathepsin B and L are related proteins that are significantly modulated through their interaction with Cystatin-B.

Mutations or dysregulation of Cystatin-B are associated with progressive myoclonus epilepsy and certain neurodegenerative diseases. The lack of functional Cystatin-B leads to excessive activity of proteases like cathepsin B resulting in increased proteolysis and neuronal damage. In some cases this can also connect to disorders involving oxidative stress exacerbating the detrimental cycle of cellular injury.
