准备和存储

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 488 under optimum conditions, and unreacted Alexa Fluor® 488 was removed.

  1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  2. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  3. The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
  4. Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
  5. Alexa Fluor® is a registered trademark of Molecular Probes, Inc., Eugene, OR.
  6. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  7. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

24a/BTK (Y551)

Bruton's tyrosine kinase (Btk) is a nonreceptor tyrosine kinase whose function is critical for proper B cell development and signaling.  The activity of Btk is regulated by Src mediated phosphorylation of the kinase domain at tyrosine 551 (Y551).  This event induces Btk kinase activity and subsequent autophosphorylation at Y223.  Phosphorylated Btk then associates with the cell membrane via the interaction of the PH domain with phosphatidylinositol 3, 4, 5-triphosphate.  

The Tec family kinase Itk plays a critical role in signal transduction downstream of the T cell antigen receptor and has been implicated in the activation of phospholipase C-γ1 (PLCγ1), a key regulator of calcium mobilization and extracellular signal-regulated kinase (ERK) activation.  Itk is regulated by an activating transphosphorylation event in which Y511 in the kinase domain is phosphorylated by Lck.  

The 24a/BTK (Y551) monoclonal antibody recognizes the Y551-phosphorylated form of human Btk and the Y511 phosphorylated form of human Itk.

Alexa Fluor™ 488
Alexa Fluor™ 488 Dye is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 517-nm. Alexa Fluor™ 488 is designed to be excited by the Blue laser (488 nm) and detected using an optical filter centered near 520-nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
