Immunology Consultants Hamster (CHO) Cathepsin B - Recombinant, 0.025mg
Recombinant CHO Cathepsin B (CTSB; UniProt G3H0L9) is expressed in CHO cells with a 6xHIS tag and purified to >95% purity. The protein appears at ~45 kDa under reducing conditions and is quantified by A280. Cathepsin B is a dual‑function cysteine protease with both endopeptidase and carboxypeptidase activity, making it a significant CHO‑derived impurity capable of fragmenting therapeutic proteins. Its presence has been linked to antibody degradation in bioprocessing. This high‑quality recombinant antigen provides a reliable standard for ELISA development, antibody generation, and impurity profiling. Its CHO‑derived structure ensures biological relevance for protease‑risk evaluation and purification optimization. A strong choice for teams developing targeted HCP detection tools or assessing protease‑driven degradation.
Biotium Resazurin Cell Viability Assay Kit
Resazurin Cell Viability Assay offers a rapid, reliable, sensitive, and cost-effective measurement of cell viability. Its performance is comparable to other commercial resazurin-based kits such as alamarBlue, PrestoBlue, or CellTiter-Blue. Cell growth maintains a reducing cellular environment while growth inhibition makes it oxidizing. Resazurin, a redox indicator, measures cell viability by monitoring conversion of oxidized, non-fluorescent resazurin (purple) to the reduced, highly red-fluorescent (blue) resorufin. The fluorescent (Ex/Em 530-560 nm/590 nm) or colorimetric (Abs. 570-600 nm) signal is proportional to the number of live, metabolically active cells. The ready-to-use, single-step, no-wash, no-lysis, homogenous assay can accurately measure as few as 80 cells. Non-toxic reagents allow long-term kinetic monitoring. The assay is non-radioactive, and non-carcinogenic and compatible with a variety of cell types including bacteria, protozoa, yeast, fungi, or mammalian cells.

Cayman Chemical CholesTRol Uptake CelBased 1ea
Maintaining body cholesterol homeostasis is critical for normal physiological functions and is achieved by a highly regulated balance of de novo synthesis, dietary cholesterol absorption, biliary clearance, and excretion. The mechanisms controlling cholesterol absorption are important to understand for the prevention and treatment of hypercholesterolemia. Cayman’s Cholesterol Uptake Cell-Based Assay Kit provides a convenient tool for studying cholesterol absorption modulators. The kit employs NBD Cholesterol, a fluorescently tagged cholesterol, as a probe for the detection of cholesterol taken up by cultured cells. U-18666A, a cholesterol intracellular trafficking inhibitor, is included as a positive control.
