Description

The CD79b antibody, clone SN8 (3A2-2E7-1F5), is generated from the hybridization of NS-1 mouse myeloma cells with spleen cells from BALB/c mice immunized with cell membrane preparations from B-prolymphocytic leukemia (B-PLL) cells.

The CD79b antibody recognizes an epitope on the extracellular domain of a 36–40 kilodalton (kDa) type I membrane glycoprotein. Immunoglobulin (Ig) antigen receptors are composed of a non-covalently associated complex of Ig and two other proteins, Igα and Igβ, which have been designated as CD79a and CD79b, respectively.

Format
  • Format FITC
  • Excitation Source Blue 488 nm
  • Excitation Max 494 nm
  • Emission Max 520 nm

FITC, fluorescein isothiocyanate, is a fluorochrome with a molecular weight of 389 Da. FITC is sensitive to pH changes and photobleaching. Due to nearly identical excitation and emission properties but different spillover characteristics, FITC and Alexa Fluor® 488 cannot be used simultaneously. FITC is relatively dim and should be reserved for highly expressed markers whenever possible.
