CA125 Protein, Human (642a.a, HEK293, His)
The CA125 protein acts by binding to MSLN and plays a crucial role in forming a protective and lubricating barrier on mucosal surfaces. This interaction promotes heterotypic cell adhesion and is suggested to play an important role in peritoneal metastasis of ovarian cancer. CA125, Human (642a.a, HEK293, His) is the recombinant human-derived CA125 protein, expressed by HEK293, with labeled tag.
- Species: Human

Description
The CA125 protein acts by binding to MSLN and plays a crucial role in forming a protective and lubricating barrier on mucosal surfaces. This interaction promotes heterotypic cell adhesion and is suggested to play an important role in peritoneal metastasis of ovarian cancer. CA125, Human (642a.a, HEK293, His) is the recombinant human-derived CA125 protein, expressed by HEK293, with labeled tag.
Background
CA125 protein is believed to serve a crucial role in establishing a protective and lubricating barrier against particles and infectious agents at mucosal surfaces. It exerts its functions through binding to MSLN, where the interaction mediates heterotypic cell adhesion. This adhesive property may play a significant role in the metastasis of ovarian cancer to the peritoneum, as CA125 initiates cell attachment to the mesothelial epithelium by binding to MSLN. The interaction between CA125 and MSLN underscores its potential involvement in the adhesive events associated with cancer metastasis, particularly in the context of ovarian cancer progression to the peritoneal cavity.

Product Properties
Lyophilized powder.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
