| Source | Biotinylated Recombinant Human Mesothelin, amino acid sequence (Glu296-Thr600) (Accession: # AAH09272.1), was expressed in 293E cells. The carboxy-terminus contains 6His-Avi tag. Human Mesothelin-Avi tag was site-specifically biotinylated by enzyme BirA. |
|---|---|
| Molecular Mass | The 341 amino acid recombinant protein has a predicted molecular mass of approximately 37.8 kD. The DTT-reduced and non-reduced proteins migrate at approximately 40 kD - 50 kD by SDS-PAGE. The predicted N-terminal amino acid is Glu. |
| Purity | > 95%, as determined by Coomassie stained SDS-PAGE. |
| Formulation | 0.22 µm filtered protein solution is in PBS, pH 7.2 |
| Endotoxin Level | Less than 0.1 EU per µg cytokine as determined by the LAL method. |
| Concentration | 25 µg size is bottled at 200 µg/mL. 100 µg size and larger sizes are lot-specific and bottled at the concentration indicated on the vial. To obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool. |
Unless otherwise stated, the minimum order amount is USD 1,000.
For orders below USD 1,000, an additional handling fee may apply, or we may arrange local delivery / local handover where available.

| Storage & Handling |
|---|
| Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin the vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week and stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles. |
| Activity | Biotinylated recombinant human Mesothelin binds to immobilized CA125/MUC16 in a dose-dependent manner using a functional ELISA. The ED50 for this effect is 0.27 – 1.35 µg/mL. |

| Application Notes | BioLegend carrier-free recombinant proteins provided in liquid format are shipped on blue ice. Our comparison testing data indicates that when handled and stored as recommended, the liquid format has equal or better stability and shelf-life compared to commercially available lyophilized proteins after reconstitution. Our liquid proteins are validated in-house to maintain activity after shipping on blue ice and are backed by our 100% satisfaction guarantee.
