Active Recombinant Human MS4A1 Protein, Fc-tagged, Alexa Fluor 555 conjugated

• Cat.No.: MS4A1-17HAF555
• Product Overview: Alexa Fluor 555 conjugated recombinant human MS4A1 (Ile 141 – Tyr 184) fussed with Fc fragment of human IgG1 tag at N-terminal was expressed in HEK293 cells.

Specification

• Source: HEK293
• Species: Human
• Tag: Fc
• Form: Lyophilized
• Bio-activity: Validated Rituximab binding in the SPR assay (Biacore T100) with the KD of 0.2 μM.
• Molecular Mass: Has a calculated MW of 32.6 kDa. Protein migrates as 42 kDa in reduced SDS-PAGE due to glycosylation.
• Protein length: Ile141-Tyr184
• Endotoxin: < 1.0 EU/ μg of the rhCD20 by the LAL method.
• Purity: > 95 % 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.
• Storage: Avoid repeated freeze-thaw cycles. No activity loss was observed after storage at:In lyophilized state for 1 year (4-8 centigrade); After reconstitution under sterile conditions for 1 month (4-8 centigrade) or 3 months (-20 to -70 centigrade).
• Storage Buffer: Lyophilized from 0.22 μm filtered solution in 50 mM tris, 100 mM glycine, pH7.5. Normally Mannitol or Trehalose are added as protectants before lyophilization.
