Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
-
Shipping
In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.

Protein Description
CHI3L1, also known as chitinase 3-like 1 or YKL-40, is a human glycoprotein that belongs to the chitinase-like family of proteins, which are implicated in various biological processes, including inflammation, tissue remodeling, and cancer progression. Elevated levels of CHI3L1 have been associated with several diseases, such as asthma, arthritis, and various cancers, where it plays a role in mediating inflammatory responses and supporting tumor growth. The protein is secreted by various cell types, including macrophages, fibroblasts, and tumor cells, and its expression can be modulated by pro-inflammatory cytokines. Research on recombinant CHI3L1 has gained momentum due to its potential as a biomarker for disease diagnosis, prognosis, and therapeutic target. Studies have investigated its role in modulating immune responses, influencing cell proliferation, and promoting angiogenesis. Furthermore, recombinant CHI3L1 is being explored as a potential therapeutic agent, as its modulation may offer new avenues for treating inflammatory and cancerous conditions. Understanding its structure and function at a molecular level through recombinant protein studies could elucidate its complex biological roles and contribute to the development of novel therapeutic strategies. These insights may enable targeted interventions that could mitigate the adverse effects associated with elevated CHI3L1 levels, ultimately leading to enhanced patient outcomes in inflammatory and oncological diseases.
