Recombinant Human CD19 Protein, Fc-tagged, Alexa Fluor 555 conjugated

• Cat.No.: CD19-408HAF555
• Product Overview: Alexa Fluor 555 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.
• Molecular Mass: 57 kDa
• Purity: > 80 % as determined by SDS-PAGE and Coomassie blue staining
• 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.
• Concentration: > 50 μg/mL as determined by microplate BCA method
• Storage Buffer: 1 × PBS, pH 7.4, 10% glycerol.
