Description

D1 Protein, Leishmania is a highly purified recombinant protein derived from the protozoan parasite *Leishmania*. This protein is a critical reagent for immunological research and diagnostic development, specifically targeting leishmaniasis. It is essential for researchers and manufacturers in the fields of parasitology, vaccine development, and serological assay production. The compound is supplied as a lyophilized powder, ensuring stability and ease of reconstitution for laboratory use.

Application

• Serological Diagnostics: Key antigen for developing and calibrating ELISA, Western Blot, and other immunoassays for leishmaniasis detection.
• Vaccine Research: Used as a target antigen in the research and development of novel vaccines against Leishmania infections.
• Immunological Studies: Fundamental tool for studying host-parasite interactions, immune response mechanisms, and antibody characterization.
• Biomarker Discovery: Employed in proteomic research to identify and validate disease-specific biomarkers.
• Quality Control Reagent: Serves as a reference standard for the quality control of commercial diagnostic kits.
• Academic & Pharmaceutical R&D: Critical component in basic research and drug discovery pipelines targeting parasitic diseases.

Quality Control

Our D1 Protein, Leishmania is produced under stringent conditions to ensure batch-to-batch consistency and high biological activity. Each lot undergoes rigorous purity analysis, including SDS-PAGE and HPLC, to confirm identity and minimize non-specific reactivity. Certificates of Analysis (COA) detailing purity, endotoxin levels, and functional activity data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store the lyophilized powder at -20°C or below for long-term stability. Upon reconstitution, aliquot and store at -80°C to avoid repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); ensure the vial is at room temperature before opening to prevent condensation.
