Singleplex Analysis
Singleplex biomarker analysis focuses on the quantitative measurement of a single, highly specific analyte within a biological sample. In contrast to multiplex assays that concurrently assess multiple targets, singleplex methodologies are engineered to isolate and quantify one particular biomarker with exceptional clarity and depth. This dedicated approach allows for meticulous optimization of assay conditions for each individual biomarker, thereby mitigating potential cross-reactivity and minimizing interference from other sample components. The outcome is data of unparalleled analytical rigor, instilling absolute confidence in every quantitative result.
Advantages of Singleplex Analysis
- Unrivaled Specificity: Singleplex assays are precisely optimized to ensure that the detection system binds exclusively to the intended biomarker, significantly reducing the occurrence of false positives. This focused approach is particularly vital when analyzing structurally similar proteins or detecting rare analytes in complex biological matrices.
- Exceptional Sensitivity and Accuracy: For numerous crucial biomarkers, especially those found at very low concentrations, singleplex platforms frequently deliver superior sensitivity and a broader dynamic range. This enables the precise quantification of analytes that may fall below the detection limits of certain multiplex systems, ensuring comprehensive and reliable results.
- Enhanced Robustness and Reproducibility: The streamlined nature of a single-analyte system often leads to improved reproducibility and inherent robustness across different experimental batches and instruments. This foundational reliability is paramount for conducting long-term studies and achieving regulatory validation for clinical applications.
- Gold Standard for Validation: Singleplex assays, notably ELISA, consistently serve as the authoritative "gold standard" for validating novel biomarkers identified through broader omics-based screening methods. Their established accuracy and dependability are essential for confirming discoveries and translating them into practical clinical utility.
Our Single Biomarker Analysis Services
Creative Biolabs provides specialized singleplex biomarker analysis services designed to accelerate your scientific discoveries and clinical development. Our team of expert biologists and assay development specialists collaborates closely with you to devise, refine, and execute singleplex assays perfectly aligned with your specific research objectives. We are equipped to deliver ultra-sensitive detection for challenging analytes, robust validation for regulatory compliance, and efficient high-throughput analysis for extensive sample cohorts.
Our team is skilled at identifying the biomarker assay option(s) with the greatest bioanalytical sensitivity and specificity that can be delivered in a defined timeline in the most economical manner.
For esoteric biomarkers not provided as kits, or kits with unfavorable performance characteristics, Creative Biolabs provides assay development services by using critical reagents such as validated antibody pairs, recombinant or native materials obtained from the client, commercial vendors, and our own laboratory.
Each assay undergoes rigorous testing to ensure high precision and accuracy, while also delivering the sensitivity and specificity required to detect biological levels of analytes.
Validation of biomarker assays usually follows the fit-for-purpose strategy whereby the degree of assay characterization corresponds to the expected context of use for the data. A minimally qualified multiplex biomarker assay can be used in a screening format to identify those biomarkers of greatest value, which can be subsequently evaluated in greater detail. Our immunology services include the development of such strategies to suit your needs and resources.
Creative Biolabs develops and validates highly selective bioanalytical methods for the quantitation of small molecule biomarkers in different matrixes. Biomarker compounds previously analyzed using LC-MS/MS include androstenediol, arginine, cAMP, cGMP, cinnamic acid, citrulline, cortisol, glutamic acid, glycosaminoglycans, and polysaccharides. Compounds such as thiamine and thiamine diphosphate can be measured using HPLC coupled with fluorescence detection.
