Validating protein expression, deciphering cellular pathways, and quantifying biomarkers require meticulous assay design and flawless execution. However, researchers often encounter critical analytical roadblocks: high background noise, antibody cross-reactivity, poor assay sensitivity, and irreproducible results. These technical hurdles consume valuable laboratory resources and delay project timelines.
At Creative Biolabs, our Custom Immunoassay Services are designed to eliminate these bottlenecks. Functioning as an extension of your own laboratory, we leverage our proprietary catalog of highly validated antibodies, recombinant proteins, and reagents to perform rigorous biological assays on your behalf. Whether your goal is mapping protein-protein interactions, quantifying low-abundance biomarkers, or profiling complex immune populations, our expert scientific team handles the entire workflow-from assay design and optimization to execution and data analysis. By outsourcing your analytical testing to the experts who understand the reagents best, you secure reliable, publication-ready data while accelerating your project timelines.
Comprehensive Immunoassay Services
We offer a diverse suite of detection and analysis services, customized to your specific sample types and research objectives. Each service is executed using optimized, target-specific protocols to ensure maximum sensitivity and minimal background interference.
Enzyme-Linked Immunosorbent Assay (ELISA) Development and Testing
Accurate quantification of low-abundance cytokines, hormones, or novel target proteins demands highly sensitive and strictly validated protocols. We design and optimize sandwich, competitive, and indirect ELISA formats. Our methodology minimizes matrix interference and establishes precise standard curves, ensuring exceptional sensitivity and lot-to-lot reproducibility for large-scale biomarker screening and pharmacokinetic profiling.
Immunofluorescence (IF)
Visualizing the exact subcellular localization, dynamic interactions, and co-expression of proteins requires highly sensitive fluorescence imaging. We overcome common IF obstacles such as severe autofluorescence and rapid photobleaching through optimized fixation methods and advanced, photostable fluorophore selection. Our IF services provide multiplexed, high-contrast imaging for cultured cells and frozen tissue sections, delivering definitive spatial data for mapping complex cellular networks.
Immunohistochemistry (IHC)
Determining tissue-specific protein expression while preserving vital morphological context is critical for translational research and preclinical pathology. We tackle challenges like poor tissue penetrance and non-specific background staining through refined antigen retrieval techniques and optimized enzymatic blocking strategies. Our IHC services offer precise chromogenic detection and quantitative digital scoring from FFPE (formalin-fixed paraffin-embedded) tissues, ensuring clear visualization of biomarker distribution within the architectural context of the tissue.
High-Resolution Western Blotting (WB)
Western Blotting remains the gold standard for protein expression profiling, yet non-specific bands and poor transfer efficiency often compromise results. Creative Biolabs offers fully optimized WB services, including custom buffer formulation, precise membrane selection, and rigorous primary/secondary antibody titration. We routinely resolve difficult targets, including high-molecular-weight proteins and heavily modified post-translational variants, providing pristine, quantifiable band density analysis.
Flow Cytometry (FC) Analysis
Analyzing heterogeneous cell populations requires multi-parametric precision. We design comprehensive flow cytometry panels to investigate immunophenotyping, cell cycle dynamics, and apoptosis. By expertly managing fluorophore compensation and spectral overlap, we deliver high-fidelity data that accurately maps complex cellular populations and drug responses.

Recommended Products
To augment our custom solutions, we offer a handpicked selection of high-performance reagents and analytical tools:
Not necessarily. We highly recommend utilizing our extensive, in-house catalog of validated primary antibodies to expedite the optimization process and reduce your costs. However, we also gladly accept and optimize assays using proprietary or third-party antibodies provided by your laboratory.
We routinely process a wide variety of sample types, including cultured cell pellets, clarified cell lysates, cell culture supernatants, serum, plasma, frozen tissue arrays, and FFPE tissue blocks. Specific sample preparation protocols will be provided before shipment to ensure antigen stability.
For IHC and IF, we employ advanced quenching protocols to neutralize endogenous peroxidases, phosphatases, and intrinsic autofluorescence. We also utilize highly cross-adsorbed secondary antibodies to ensure signal specificity and eliminate species cross-reactivity in multi-labeling experiments.
Project timelines scale with complexity. Routine detection using validated, commercially available kits can be completed within 2 to 4 weeks. Custom assay development, encompassing extensive optimization and rigorous validation phases, typically requires 4 to 10 weeks. A detailed, transparent project schedule is provided during our initial consultation.
