HOUSTON, May 14, 2026 /PRNewswire/ — Elabscience^(®) Bionovation Inc. ("Elabscience
^(®)" or "the Company") today announced the launch of its self-developed PolyHRP-
Streptavidin conjugate, a signal amplification reagent designed to improve enzyme-
linked immunosorbent assay (ELISA) sensitivity for low-abundance biomarker detection.
Using proprietary covalent polymerization technology, the reagent creates a one-
to-many amplification structure that strengthens detection signals while maintaining
low background interference.

Elabscience^(®) developed its PolyHRP-Streptavidin conjugate to address a common
ELISA challenge in which very low biomarker concentrations can make it difficult
to increase signal output without also raising background noise. The product is 
built on a proprietary covalent coupling technique designed to create a more efficient
amplification structure than traditional Streptavidin-HRP conjugates. In this process,
a large number of highly active HRP enzymes are first polymerized to form a PolyHRP
backbone, which is then conjugated to streptavidin. This one-to-many architecture
increases the enzyme-to-protein ratio and enables cascade signal amplification which
helps to improve assay sensitivity in low-abundance biomarker detection.

Dr. Yang Fei, General Manager of Elabscience^(®), commented: "Sensitivity and stability
are critical requirements in ELISA reagent development, especially when researchers
are working with low-abundance targets. With our self-developed [**PolyHRP-Streptavidin**](https://www.elabscience.com/p/polyhrp-streptavidin--e-elir-020)
conjugate, we aim to provide researchers and assay developers with a reliable signal
amplification tool that supports stronger detection performance, lower background
interference and long-term reagent stability."

Validation data showed strong performance across several key measures. SEC-HPLC 
analysis of three independent batches demonstrated an approximately 90% product 
recovery rate, with a peak area coefficient of variation of 2.9%, indicating high
batch-to-batch consistency. Nanoparticle tracking analysis also showed a narrow 
particle size distribution centered at about 155 nm which supports the uniformity
of the PolyHRP-Streptavidin polymer structure.

In internal performance testing, Elabscience^(®) PolyHRP-Streptavidin delivered 
strong signal intensity while maintaining low background signal. Accelerated stability
testing at 37°C showed over 90% remaining activity after 11 days, demonstrating 
strong reagent stability under accelerated conditions. The product is also designed
for broad compatibility across standard ELISA, [**high-sensitivity ELISA**](https://www.elabscience.com/search?category=high-sensitivity-elisa-kits)
and competitive ELISA workflows.
