Recombinant Human CD19 Protein, Fc-tagged, Alexa Fluor 488 conjugated

• Cat.No.: CD19-408HAF488
• Product Overview: Alexa Fluor 488 conjugated recombinant human CD19, transcript variant 2, fused with Fc tag at C-terminal was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Description: Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. This gene encodes a cell surface molecule which assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.

  Labeled with Alexa Fluor 488 via amines
  Excitation Wavelength: 488 nm
  Emission Wavelength: 515­-545 nm
• Concentration: > 50 μg/mL as determined by microplate BCA method
