The E.coli HCP (Alkaloid Cleavage) ELISA Kit from MtoZ Biolabs is a quantitative immunoassay developed for measuring residual Escherichia coli host cell proteins in samples processed by alkaloid or alkaline cleavage workflows, supporting impurity monitoring in plasmid and recombinant product manufacturing.
Product Overview
Residual E. coli host cell proteins are key process-related impurities in microbial expression systems, particularly in workflows involving alkaloid or alkaline cleavage. Accurate HCP measurement requires an assay compatible with both the treated protein profile and the associated sample matrix. Key considerations include:
1. Process-Modified HCP Recognition
Alkaloid or alkaline cleavage can alter HCP structure and immunoreactivity, requiring assays that maintain reliable antibody binding after treatment.
2. Compatibility With Alkaline Lysis-Derived Samples
Crude and intermediate fractions generated during plasmid extraction present complex matrices that can affect assay specificity and signal stability.
3. Coverage Across Common E. coli Clones
Broad strain reactivity is essential for consistent HCP quantitation across commonly used laboratory and production strains.
Advantages
The MtoZ Biolabs E.coli HCP (Alkaloid Cleavage) ELISA Kit provides the following advantages:
1. Proces-Relevant Design
Optimized for samples subjected to alkaloid or alkaline cleavage, improving alignment between assay performance and actual process conditions.
2. Broad Strain Applicability
