Active Recombinant Mouse Cd19 Protein, His-tagged, Alexa Fluor 555 conjugated

• Cat.No.: Cd19-3308MAF555
• Product Overview: Alexa Fluor 555 conjugated recombinant Mouse Cd19 Protein (Met1-Gly287) is produced by HEK293 Cells expression system. This protein is fused with a His tag at the C-terminal.

Specification

• Source: HEK293
• Species: Mouse
• Tag: His
• Form: Lyophilized
• Bio-activity: Measured by its ability to bind with human CD9-His in a functional ELISA.
• Molecular Mass: 31 kDa
• Protein length: Met1-Gly287, 282
• N-terminal Sequence Analysis: Gly 17
• Endotoxin: < 1.0 EU/ μg of the protein as determined by the LAL method.
• Purity: > 90 % as determined by SDS-PAGE
• Characteristic: Disulfide-linked homodimer
  Labeled with Alexa Fluor 555 via amines
  With an excitation and emission maximum of 555/565 nm, Alexa Fluor 555 can be efficiently excited using a 543 nm He-Ne laser line and detected under standard TRITC/Cy3 filters.
• Stability: Samples are stable for up to 12 months from date of receipt at -70 centigrade.
• Storage: Store it under sterile conditions at -20 to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Storage Buffer: Lyophilized from sterile PBS, pH 7.4. Normally 5%-8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
• Shipping: Shipped at ambient temperature.
  Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
