Expand Life Science Research with MyBioSource Highly Validated CTSB Recombinant Protein

MyBioSource’s added Ctsb Recombinant Protein in their Product Line

SAN DIEGO, CA, UNITED STATES, July 29, 2025 /EINPresswire.com/ -- MyBioSource, a global leader in delivering the highest quality research reagents, is announcing the expansion of its recombinant protein product line with the release of Ctsb recombinant protein (Cathepsin B, MBS952553).

The objective of this new offering is to widen the scope of life science research for advanced proteomics and cellular studies.

Ctsb recombinant protein is a lysosomal cysteine protease that is integral for intracellular protein degradation, turnover, and for a variety of cellular processes.

In biomedical research, Cathepsin B (Ctsb) is used by researchers to understand the molecular mechanisms of complex biological phenomena and also to understand why the overexpression or dysregulation of Ctsb can cause medical issues in several pathological conditions, including neurodegenerative disorders and tumor progression.

The Scope of CTSB Recombinant Protein in Research

To meet the diverse needs of experiments, the Ctsb recombinant protein delivered by MyBioSource is made available in multiple host expression systems such as baculovirus, E.coli, yeast, and mammalian cells.

The rProtein is designed to boast a minimum purity of 85% which is determined by SDS-PAGE. It is available in liquid format (lyophilized), and based on information on N-terminal and C-terminal tags, can be custom prepared as well.

Based on experimental requirements, researchers can select optimal expression systems to ensure maximum activity and consistency across in vitro studies.

Research-Only Product for Trusted Scientific Applications

The research reagent at MyBioSource is offered exclusively for research purposes and not for diagnostic and therapeutic applications. The primary uses include:

*In-depth understanding of the mechanism of protein turnover and degradation within lysosomes.
*For the elucidation of Ctsb’s role in tissue homeostasis, extracellular matrix remodeling, and immune response.
*What are its uses as a positive control, especially in the case of enzymatic assays, antibody generation, and biochemical characterization?
*A keen understanding of Ctsb’s function as an amyloid precursor protein secretase in neurodegeneration research.
*It can also be used for the study of cancer biology, like in the case of metastasis and tumor invasion.


The lot is manufactured under ISO 9001:2015 certified conditions with the purpose of ensuring premium quality and reproducibility with full regulatory compliance for laboratory research worldwide.
