A_H4B4_FITC_CD107b_Antibody_1_FC_011316
Human acute myeloid leukemia cell line KG1a was fixed, permeabilized, and stained with CD107b (clone H4B4) PE (filled histogram) or mouse IgG1, κ PE isotype control (open histogram).
  • A_H4B4_FITC_CD107b_Antibody_1_FC_011316

  • B_H4B4_PURE_CD107b_Antibody_2_IHCP_022819
    Human paraffin-embedded prostate tissue slice was stained with purified anti-human CD107b (clone H4B4) followed by goat anti-mouse IgG (clone Poly4053) DyLight™ 488 (green) and anti-human CD44 (clone IM7) Alexa Fluor® 594 (red). The nuclei were counterstained with DAPI (blue). The image was captured with a 10X objective. See additional supplemental data for detailed information.
  • C_H4B4_PURE_CD107a_LAMP1_ICC_022718
    ICC staining of purified anti-LAMP-2 antibody (clone H4B4) on Hela cells. The cells were fixed with 4% PFA, permeabilized with 0.1% Triton X-100, and blocked with 2% normal goat serum and 0.02% BSA. The cells were then stained with 5 µg/ml of the primary antibody overnight at 4°C, followed by incubation with Alexa Fluor® 594 goat anti-Mouse IgG (Cat. No. 405326) for one hour at room temperature. Cells were counterstained with Phalloidin™ Green 488 (Cat. No. 424201) and DAPI to visualize actin filaments and nuclei, respectively. The images were captured with a 60X objective. Scale bar: 50 µm.
  • D_H4B4_PURE_CD107a_LAMP1_WB_022718
    Western blot of purified anti-LAMP-2 antibody (clone H4B4). Lane 1: Molecular weight marker; Lane 2: 20 µg of Hela cell lysate; Lane 3: 20 µg of NIH3T3 cell lysate; Lane 4: 20 µg of human brain lysates; Lane 5: 20 µg of mouse brain lysates; Lane 6: 10 ng human recombinant LAMP-2. The blot was incubated with 1 µg/ml of the primary antibody overnight at 4°C, followed by incubation with HRP-labeled goat anti-mouse IgG (Cat. No. 405306). Anti-β-actin antibody was used as the loading control (Cat. No. 643807). Enhanced chemiluminescence was used as the detection system.

Description

CD107b, also known as LAMP-2, is a 105 kD, highly gylcosylated, type I transmembrane protein. CD107b is expressed in lysosomal/endosomal membranes in nearly all cells, and on the surface of activated platelets, activated lymphocytes and some tumor cell lines.  LAMP-2 is known to have roles in cell adhesion and cellular homeostasis, including autophagocytosis and antigen presentation.

Recommended Usage

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.5 µg per million cells in 100 µl volume. For immunohistochemical staining on formalin-fixed paraffin-embedded tissue sections, the suggested use of this reagent is 5.0 - 10 µg per ml. For Western blotting, the suggested use of this reagent is 1.0 - 5.0 µg per ml. For immunocytochemistry, a concentration range of 5.0 - 10 μg per ml is recommended. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Additional reported applications (for the relevant formats) include: immunohistochemical staining of frozen glomeruli2 and immunofluorescent staining of  neutrophils2,3.

This antibody is specific to human LAMP-2. Positive control: Hela cells; LAMP-2 molecular weight appears to be at ~110 kDa on the gel due to high glycosylation.
