Description

The H4B4 monoclonal antibody specifically binds to CD107b. CD107b is a heavily glycosylated, ~120 kDa type I transmembrane protein that is also known as lysosomal-associated membrane protein 2 (LAMP-2/LAMP2), LAMPB, or LGP110. CD107b is expressed in the lysosomal and endosomal membranes of most cell types where it may play a role in maintaining membrane integrity. CD107b is also expressed on the surface of activated platelets and lymphocytes, including T lymphocytes, e.g., degranulating CD8+ cytotoxic T cells. CD107b serves as a ligand for selectins, including E-selectin, and mediates cellular adhesion. CD107a/ LAMP-1 and CD107b /LAMP-2 are carriers for poly-N-acetyllactosamines, and display the sialyl Le[x] antigen. CD107b is likewise expressed on some tumor cells and cell lines, including U937 and KG1a, and may facilitate tumor metastases.

Format
  • Format Alexa Fluor® 647
  • Excitation Source Red 633 nm
  • Excitation Max 650 nm
  • Emission Max 668 nm

Alexa Fluor® 647 conjugates are highly photostable and remain fluorescent over a broad pH range. The excitation and emission maxima are nearly identical to those of APC. However, APC tends to be brighter while Alexa Fluor® 647 is more optimal for intracellular applications. This fluorochrome exhibits uncommon photostability, making it an ideal choice for use in fluorescence microscopy. Due to nearly identical excitation and emission properties but different spillover characteristics, APC and Alexa Fluor® 647 cannot be used simultaneously.

Preparation and Storage

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® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.

Product Notices

  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. An isotype control should be used at the same concentration as the antibody of interest.
  3. 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.
  4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  5. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
  6. 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.
