MtoZ Biolabs' CHO Host Cell Proteins Polyclonal Antibody is a highly specific antibody designed to detect and quantify residual Chinese hamster ovary (CHO) host cell proteins (HCPs) in recombinant biologics, ensuring the purity of biopharmaceutical products and compliance with regulatory standards.
Product Overview
The detection of residual HCPs in CHO cell-derived therapeutics is challenging due to the complexity of the host cell proteins and the interference from high product concentrations during purification. Common challenges include:
1. Limited Sensitivity
Residual CHO HCPs can persist at trace levels after purification, and low-intensity signals are easy to miss or fall below the assay detection range. This increases the risk of underreporting residuals, especially when you need confident trending across process steps or lots.
2. Non-Specific Binding
High concentrations of the target biologic, along with formulation components (salts, detergents, excipients), can elevate background and promote nonspecific binding. The result is reduced signal-to-noise, false positives, or masked HCP signals that make quantitation less reliable.
3. Batch-to-Batch Variability
If antibody reactivity shifts between lots, the same sample can yield different readouts over time. This complicates longitudinal monitoring, cross-batch comparisons, and method transfer, and it can trigger extra verification work during QC and validation.
4. Incompatibility with Certain Downstream Assays
Limited compatibility can force workflow changes, extra optimization, or parallel reagents to support different readouts and development stages.
