High-Performance Hormone Antibodies for IVD & Research
Precision Clones for Reproductive Health, Thyroid Function, and Endocrine Biomarkers.
From Feasibility to Commercial Scale
Leinco Technologies offers a dynamic portfolio of high-affinity monoclonal antibodies and antigens designed for the rigorous demands of In Vitro Diagnostic (IVD) assay development and basic research. Whether you are developing sensitive Lateral Flow Assays (LFA) or quantitative ELISAs, our reagents support your project from Phase 1 feasibility through to commercial manufacturing.
Our portfolio includes rigorously validated clones for fertility, thyroid, and adrenal testing, manufactured under ISO 13485:2016 and cGMP standards to ensure lot-to-lot consistency and regulatory compliance.
Key Product Categories
1. Reproductive Health & Fertility Diagnostics
Detect pregnancy and monitor reproductive health with high-sensitivity antibodies targeting key gonadotropins. Our matched pairs are optimized for detecting low hormone concentrations, critical for early pregnancy and fertility screening.
- Human Chorionic Gonadotropin (hCG): We offer specific clones for hCG Beta (e.g., Clone 152, Clone 208), Intact hCG and free beta hcg.
- Performance: Detection limits (LoD) as low as ≤3.125 mIU/mL in lateral flow formats.
- Specificity: Low cross-reactivity with LH, FSH, and TSH.
- Follicle Stimulating Hormone (FSH): Clones targeting FSH Beta (e.g., Clone 181) for evaluating ovarian function and menopause.
- Luteinizing Hormone (LH): High-specificity LH Beta antibodies (e.g., Clone 196, Clone 199) for ovulation tracking and pituitary function assessment.
- Prolactin (PRL): Antibodies (e.g., Clone 174, Clone 172) validated for detecting pituitary disorders and hyperprolactinemia.
- PAPP-A: Pregnancy Associated Plasma Protein A (Clone PAPP-6611) for prenatal screening and cardiovascular risk assessment.

2. Thyroid Function & Metabolic Panels
Develop robust thyroid panels with our purified antibodies for the pituitary-thyroid axis.
- Thyroid Stimulating Hormone (TSH): Antibodies targeting TSH Beta (e.g., Clone 154, Clone 195).
- Performance: Reliable dose-response in LFA with LoD estimates of ≤125 μIU/mL.
- Thyroxine (T4): Monoclonal antibodies (e.g., Clone 161) specific for T4 with <1% cross-reactivity to T3 or rT3, essential for diagnosing hypothyroidism and hyperthyroidism.
3. Adrenal Function & Stress Biomarkers
- Cortisol: Anti-Cortisol (Clone 14D5) is highly specific for the steroid hormone cortisol, enabling accurate diagnostics for adrenal disorders such as Cushing’s syndrome and Addison’s disease.
Applications
Our hormone antibodies are validated for use in a variety of immunoassay formats:
- Lateral Flow Assays (LFA): High-intensity test lines and robust controls for rapid diagnostics.
- ELISA: Validated matched pairs for Sandwich and Competitive ELISA formats.
- Automated Immunoassay Platforms: Reagents suitable for magnetic bead and chemiluminescence systems.
