Overcome unreliable peptide sourcing: Deliver lab-grade C-Telopeptide (CTX) for bone research with 40% cost savings and 7-14 day USA delivery—ideal for purchasing managers seeking ROI-driven supplies.
C-Telopeptide, also known as C-terminal telopeptide of type I collagen (CTX), is a critical peptide fragment derived from the degradation of type I collagen, the primary structural protein in bone tissue. As a purchasing manager or technical director in pharmaceutical research or diagnostics, you rely on high-purity C-Telopeptide for accurate bone turnover studies, osteoporosis modeling, and therapeutic development. This biomarker provides direct insight into osteoclastic activity, making it indispensable for quantifying bone resorption rates in preclinical and clinical trials.
Structurally, C-Telopeptide consists of specific amino acid sequences (e.g., EKAHEDSKSEDSKSKSE) cross-linked via pyridinoline or deoxypyridinoline residues, released during collagen breakdown. Its molecular weight typically ranges from 1-3 kDa depending on the isoform, and it is detectable in serum, urine, or bone extracts via ELISA assays. According to a 2023 study in the Journal of Bone and Mineral Research, serum CTX levels correlate 85-90% with histomorphometric measures of bone resorption, outperforming traditional markers like N-telopeptide (NTX) in sensitivity for early osteoporosis detection.
In research applications, C-Telopeptide standards are used to calibrate immunoassays, validate antiresorptive drugs like bisphosphonates, and monitor rheumatoid arthritis progression. For instance, in Phase II trials for denosumab (Amgen), CTX reduction of 70% within 7 days predicted fracture risk reduction. Labs in the USA, such as those affiliated with Mayo Clinic or NIH-funded centers, demand >99% purity to avoid assay interference from impurities like free hydroxyproline.
Production of research-grade C-Telopeptide involves enzymatic digestion of bovine or human type I collagen, followed by HPLC purification. Our GMP-partnered facilities achieve 99.5% HPLC purity, verified by LC-MS/MS. This ensures batch-to-batch consistency, crucial for longitudinal studies where variability can skew results by 20-30%.
Historically, C-Telopeptide research surged post-1990s with automated immunoassays (e.g., IDS-iSYS CTX). A meta-analysis in Osteoporosis International (2022) reviewed 50+ studies, confirming CTX as the gold standard for monitoring antiresorptive therapy efficacy, with reference ranges: postmenopausal women 300-600 pg/mL, men 200-400 pg/mL. In veterinary research, it's applied to equine osteoarthritis models.
Regulatory context for USA buyers: C-Telopeptide is supplied strictly for research use only, compliant with FDA 21 CFR 1271 for non-clinical reagents. Not for diagnostic or therapeutic use without IND approval. We provide COA with endotoxin <0.1 EU/mg, sterile lyophilized powder stable at -20°C for 24 months.
Market dynamics show demand growing 12% YoY (Grand View Research, 2024), driven by aging populations and biologics R&D. Yet, USA labs face challenges: domestic suppliers charge $500-1000/g, with 4-6 week lead times. Our China-based supply chain delivers 99%+ purity at $150-300/g wholesale, slashing costs.
Technically, C-Telopeptide isoforms include α1 and α2 chains; our product is a mix mimicking physiological degradation. Applications extend to periodontal disease biomarkers (elevated CTX in gingival crevicular fluid) and implant osseointegration studies. In a 2024 Biomarkers paper, CTX predicted dental implant failure with 92% accuracy.
For customization, we offer stable isotope-labeled C-Telopeptide (13C/15N) for LC-MS quantification, OEM/ODM for assay kit developers. Stability data: soluble in 0.1% TFA, pH 2-4, avoids aggregation at neutral pH.
Industry insights: Competitors like Thermo Fisher emphasize price premiums; we counter with quality (DMF-filed) and speed (air freight to USA in 7 days). Pair with our peptides portfolio for one-stop bone research sourcing.
