Description

Engrailed Protein, Bombyx is a specific developmental regulatory protein derived from the silkworm, Bombyx mori. This protein plays a crucial role in fundamental biological research, particularly in the study of insect embryogenesis, segmentation, and nervous system development. It is an essential reagent for molecular biologists, geneticists, and entomologists working in academic research, biotechnology, and pharmaceutical discovery to understand gene regulation and protein function.

Application

• Developmental Biology Research: Key reagent for studying the genetic control of segmentation and body plan formation in Bombyx mori and related insects.
• Neuroscience Studies: Investigation of neural development and the specification of neuronal identities during embryogenesis.
• Protein-Protein Interaction Assays: Used in pull-down, co-immunoprecipitation, or yeast two-hybrid screens to identify interacting partners in signaling pathways.
• Antibody Production & Validation: Serves as a high-purity antigen for generating and testing specific polyclonal or monoclonal antibodies.
• Gene Expression Analysis: Used as a control or target in studies involving quantitative PCR, in situ hybridization, and Western blotting to analyze engrailed gene expression patterns.
• Educational & Reference Standard: Provides a defined protein standard for university-level teaching and laboratory method validation in molecular biology.

Quality Control

Our Engrailed Protein, Bombyx is produced and handled under stringent conditions to ensure batch-to-batch consistency and biological activity. Each lot is subjected to rigorous analytical testing, including purity assessment and functional validation. A comprehensive Certificate of Analysis (COA) detailing identity, purity, concentration, and biological activity is provided with every shipment to support your research integrity.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature before opening to minimize moisture condensation. For extended storage, consider aliquoting to avoid repeated freeze-thaw cycles.
