Chitinase-3 like-protein-1 (CHI3L1), one of the CLPs, also has been named YKL-40 in humans and breast regression protein 39 (BRP-39) in mice, is common in both prokaryotes and eukaryotes. Following its initial discovery in the culture supernatant of the osteosarcoma cell line MG63, it was subsequently detected in human chondrocytes, synoviocytes, and vascular smooth muscle cells. In fact, CHI3L1 is produced by a multitude of cells, including macrophages, neutrophils, fibroblast-like cells, hepatic stellate cells, endothelial cells, and cancer cells. CHI3L1 is overexpressed in many human cancer types and animal tumor models, for instance, oligodendroglia, glioblastoma, osteosarcoma, sarcoma, colon, and gastric cancers (GCs). Elevated serum levels of CHI3L1 have been found to be associated with poor prognosis and shorter survival in patients with metastatic cancer. Consequently, CHI3L1 has been increasingly proposed as a sensitive biomarker and an attractive therapeutic target for several certain types of cancers.

流式分析
Flow cytometric analysis of 4% PFA fixed 90% methanol permeabilized 293T (Human embryonic kidney epithelial cell, left) / THP-1 (Human monocytic leukemia monocyte, Right) labelling CHI3L1 antibody at 1/500 dilution (0.1 μg) / (Red) compared with a Rabbit monoclonal IgG (Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). Goat Anti - Rabbit IgG Alexa Fluor® 488 was used as the secondary antibody.
Negative control: 293T
免疫组化
IHC shows positive staining in paraffin-embedded human kidney. Anti-CHI3L1 antibody was used at 1/400 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.

免疫细胞化学
ICC shows positive staining in THP-1 cells. Anti-CHI3L1 antibody was used at 1/500 dilution (Green) and incubated overnight at 4°C. Goat polyclonal Antibody to Rabbit IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. The cells were fixed with 100% ice-cold methanol and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue).

FAQs
我们一般不推荐客户回收利用抗体。 因为抗体使用之后缓冲体系已经发生改变，不同客户在回收抗体的保存条件上也会有差异，所以抗体回收使用效果无法保证。另外，我们对一批抗体回收验证测试，测试结果显示不同抗体可回收次数不同，一般效价越高的抗体，可重复使用的次数越多，客户可根据实验情况来确定
