Product Description

Human CA19-9 cancer antigen is a glycoprotein biomarker primarily associated with gastrointestinal malignancies. Belonging to the sialylated Lewis blood group antigen family, CA19-9 is commonly used in clinical settings for the diagnosis, prognosis, and monitoring of pancreatic and colorectal cancers. With a molecular weight of approximately 200-300 kDa, this tumor-associated antigen is detected through serological tests and serves as a valuable tool in cancer management. Its significance lies in its ability to aid in the early detection and assessment of therapeutic response, contributing to improved patient outcomes.

If your product is within its expiration period, and has not performed according to expectations, fill out the sample return form. Return the unused sample frozen, with the auto generated packing slip to the address on the instructions. You will receive a full refund along with a replacement of the unused portion (inclusive of the failed test). Damages do not cover any additional costs incurred for failed experimentation. 

Reconstituted store at -20°C or -80°C.We recommend that single use aliquots are prepared to avoid freeze-thaw cycles.

1. Thaw the vial on ice, spin briefly
2. Prepare single-use or stock aliquots. This stage will depend on your final application so please adapt as appropriate. All our proteins are supplied carrier protein-free. If compatible with your work and you are storing at lower concentrations (<50 ug/ml) adding carrier protein is highly advised (usually 1% w/v high purity BSA or equivalent – ensure all buffers are sterile-filtered).
3. Prepare single-use aliquots whenever possible to avoid freeze-thaw cycles which can damage the proteins and reduce bioactivity. Store aliquots at -70 °C (or -20 °C)
4. We recommend sterile filtering after dilution in media or the final working solution
