E.coli HCP ELISA Kit

Product Introduction


Escherichia coli (E.coli), commonly known as coliform bacteria, is a host cell line widely used in biotechnology and biopharmaceutical industries. Since E.coli expression host cell proteins (HCPs) can affect the activity of biological products, it is essential to detect and control E.coli HCP residues during the production of biological products.
Junyan Biotech’s E.coli Expression HCP Residual Detection Kit is a highly sensitive assay designed to detect host cell protein (HCP) residues derived from E.coli BL21 strains in biological products. The kit enables sensitive, specific, and accurate detection of E.coli BL21 HCP residues at various process stages of biological product manufacturing.


Advantages and Features


  • High Antibody Coverage: Broad antibody panel ensures full lifecycle product compatibility.

  • Strong Specificity: No cross-reactivity with BSA, Protein A, HEK293 HCP, or CHO HCP.

  • Superior Performance: Excellent standard curve linearity, high accuracy, good repeatability, and qualified sample spike recovery rates.


Performance Indicators


  • Reaction System: 2 hours + 20 minutes

  • Limit of Quantitation (LOQ): 1.1 ng/mL

  • Detection Range: 1.1–270 ng/mL

  • Spike Recovery Rate: 80%–120%

  • Limit of Detection (LOD): ≤0.4 ng/mL

  • Repeatability (Intra-Batch CV): ≤15%
