Description

P70 Protein, Xenopus is a highly purified recombinant protein derived from Xenopus laevis, a key model organism in developmental and cell biology research. This product is essential for researchers studying cell cycle regulation, DNA replication, and protein-protein interactions in a controlled biochemical context. It is primarily utilized by academic, pharmaceutical, and biotechnology laboratories engaged in fundamental life science research and drug discovery programs. The protein is supplied in a lyophilized format to ensure stability and long-term storage viability.

Application

• Biochemical Research: Used as a critical reagent in in vitro assays to study the mechanisms of cell cycle progression and checkpoint control.
• Protein Interaction Studies: Employed in pull-down assays, co-immunoprecipitation (Co-IP), and surface plasmon resonance (SPR) to map interaction networks.
• Enzymatic Activity Assays: Serves as a substrate or co-factor in kinase, phosphatase, or ubiquitination activity assays to elucidate signaling pathways.
• Antibody Production & Validation: Acts as a high-purity immunogen for generating specific polyclonal or monoclonal antibodies.
• Structural Biology: Provides material for X-ray crystallography or cryo-electron microscopy studies to determine protein structure-function relationships.
• Educational & Diagnostic Development: Used in advanced teaching laboratories and as a component in the development of research-grade diagnostic tools.

Quality Control

Our P70 Protein, Xenopus is produced under stringent conditions to ensure batch-to-batch consistency and high biological activity. Each lot undergoes rigorous quality testing, including purity assessment by SDS-PAGE and HPLC, functional activity validation in relevant biochemical assays, and endotoxin level testing. A comprehensive Certificate of Analysis (COA) detailing identity, purity, concentration, and biological activity is provided with every shipment to support your research compliance and reproducibility requirements.

Storage

Preserve in a tightly closed container, protected from light. For long-term storage, keep the lyophilized powder at -20°C or below. The product is hygroscopic (moisture-sensitive); ensure the container is sealed under anhydrous conditions after each use. Reconstituted protein aliquots should be stored at -80°C and used promptly to avoid repeated freeze-thaw cycles.
