Headquartered in Xiangyang, our campus integrates solid-phase peptide synthesis, downstream isolation, and analytical release under one quality system. The site is purpose-built for milligram-to-kilogram research-grade output, with environmental controls calibrated for sensitive sequences and copper-bound complexes.
Escribir el tiempo a la escala de los átomos
Los péptidos son cadenas cortas de aminoácidos unidas por enlaces peptídicos precisos. Son el lenguaje que utilizan las células para coordinar el metabolismo, la reparación y el envejecimiento. En Xiangyang Lizhi aplicamos el rigor molecular a la biología del tiempo.
Síntesis en fase sólida
SPPS automatizada con química Fmoc para secuencias de más de 60 residuos, con rendimiento reproducible.
Purificación cromatográfica
HPLC de fase reversa preparativa e intercambio iónico. Cromatograma independiente para cada lote.
Caracterización estructural
Triple confirmación cruzada mediante MALDI-TOF, LC-MS y RMN.
Estudios de estabilidad
Estabilidad acelerada y a largo plazo conforme a las directrices ICH, garantizando la vida útil para nuestros socios.
Nitrogen, chilled water, and inert-gas lines feed the reaction hall directly. Continuous utilities are what allow Fmoc deprotection and coupling cycles to run without drift in temperature or atmosphere — the invisible infrastructure behind every peptide bond formed on site.
Solvent is stripped from a synthesis intermediate on a rotary evaporator under reduced pressure. This is the unglamorous middle of the route: each crude peptide is concentrated, exchanged, and prepared for cleavage before it ever sees a purification column.
From sterile bulk to sealed vial, without contact with the operator.
Filtered peptide solution is metered into siliconised borosilicate vials inside a Grade A air stream. Stopper insertion and crimp closure happen in line, so the molecule moves from compounding tank to sealed primary container without an open transfer step. What enters the lyophiliser is what we synthesised — nothing added, nothing lost.

Moléculas creadas para la investigación
Diecisiete insumos peptídicos representativos de calidad para investigación. Cada molécula incluye su información estructural, mecanismo y dirección de investigación.
A reversed-phase HPLC column resolves the target peptide from synthesis-related impurities; the same column data later anchors the certificate of analysis. Beside it sits the freeze-dryer, where the purified solution is taken below 0.05 mbar and slowly sublimed into a porous lyophilised cake stable for years at -20 °C.
Vials emerge from the lyophiliser onto a stainless tray for 100% visual inspection: cake structure, fill height, closure seating, and absence of particulates. Only vials that pass this check are crimped, labelled, and assigned a release batch number — every other vial is destroyed.
El tiempo es irreversible. Pero puede comprenderse.
Creemos que el envejecimiento es un proceso biológico que puede estudiarse. Xiangyang Lizhi pone el rigor químico en manos de instituciones académicas, farmacéuticas de I+D y laboratorios preclínicos, para que cada molécula se convierta en una herramienta que amplíe nuestra comprensión de la vida.

Inside the reaction hall.
A technician verifies temperature and stirring on a jacketed stainless reactor during a peptide-coupling step. Every cycle is logged against the batch record: reagent lot, equivalents, time, and in-process control. Nothing about a peptide bond is improvised here.
A single vial. A single sequence.
The porous white cake at the bottom of the vial is the peptide itself, frozen out of solution and dried under vacuum until only the molecule remains. Stable, dose-accurate, and ready to be reconstituted in bacteriostatic water under research conditions — exactly as it left our analytical release.

Con sede en Xiangyang, Hubei. Nuestro nombre proviene de los milenarios lichis de la ciudad, símbolo del regalo de la naturaleza y de la paciencia del tiempo. Nos dedicamos a la investigación de péptidos bioactivos y al suministro de insumos para la comunidad global de longevidad y medicina regenerativa.
Analysts overlay the current batch chromatogram against the reference standard. Identity, retention time and main-peak area are confirmed before the batch number is ever issued. This is the last gate between synthesis and the certificate of analysis attached to your vial.
Sensitive reagents and protected amino acids are weighed and transferred under extraction. The same gloved hands that build a tripeptide today have built thousands before it; that continuity is the difference between a research-grade sequence and a batch.
