Polyclonal Antibody to Chitinase-3-like Protein 1 (CHI3L1)

GP39; CHI3-L1; YKL40; Chondrex; Chitinase 3-Like 1; Chondrocyte Protein YKL40; 39 kDa synovial protein


The antibody is a rabbit polyclonal antibody raised against CHI3L1. It has been selected for its ability to recognize CHI3L1 in immunohistochemical staining and western blotting.


Western blotting: 0.5-2µg/mL
Immunohistochemistry: 5-20µg/mL
Immunocytochemistry: 5-20µg/mL
Optimal working dilutions must be determined by end user.


Store at 4°C for frequent use. Stored at -20°C in a manual defrost freezer for two year without detectable loss of activity. Avoid repeated freeze-thaw cycles.


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°C for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.
