  Mass Cytometry - Anti-CD68 antibody [KP1] - BSA and Azide free (ab233172)

  Imaging Mass Cytometry™ (IMC™) image of human tonsil tissue stained with Anti-CD68 antibody [KP1]. ab233172 (carrier-free antibody, purified) was metal-conjugated using a Maxpar® Antibody Labeling Kit from Fluidigm. Immunostaining was performed according to Fluidigm's protocols. Briefly, slides were subject to deparaffinization and heat-induced epitope retrieval, followed by overnight incubation at 4°C with an antibody cocktail containing metal-tagged antibodies in blocking buffer. Slides were subsequently washed with 0.2% Triton-X and 1x PBS, counterstained with Cell-ID™ Intercalator-Ir diluted at 1/400 in 1x PBS for 30 min at room temperature, rinsed for 5 min with distilled H2O, and air-dried prior to IMC™ acquisition. IMC™ acquisition was performed using the Fluidigm Hyperion™ Imaging System.

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD68 antibody [KP1] - BSA and Azide free (ab233172)

  CD68 immunohistochemistry staining of human liver using mouse anti-CD68 antibody
  
  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human liver tissue labelling CD68 with Anti-CD68 antibody [KP1] ab955 at 1/3000 dilution. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9. Antigen Retrieval Buffer (100X Tris-EDTA Buffer, pH 9.0) ab93684 a Goat Anti-mouse IgG H&L (HRP) was used as the secondary antibody. Negative control using PBS instead of primary antibody. Counterstained with hematoxylin.

  Cytoplasmic staining on Kupffer cells of human liver (PMID: 12118106).

  This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (Anti-CD68 antibody [KP1] ab955).

  Immunocytochemistry/ Immunofluorescence - Anti-CD68 antibody [KP1] - BSA and Azide free (ab233172)

  Immunofluorescent analysis of 100% methanol-fixed THP-1 (human monocytic leukemia cell line) cells labeling CD68 with ab233172 at 1/50 dilution, followed by Goat Anti-Mouse IgG H&L (Alexa Fluor^® 488) (Goat Anti-Mouse IgG H&L (Alexa Fluor® 488) ab150113) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic staining in THP-1 cells. The nuclear counter stain is DAPI (blue). Tubulin is detected with Recombinant Anti-beta IV Tubulin antibody [EPR16775] (Anti-beta IV Tubulin antibody [EPR16775] ab179504) at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 594) (Goat Anti-Rabbit IgG H&L (Alexa Fluor® 594) ab150080) secondary antibody at 1/1000 dilution (red).
  

  Secondary antibody only control: Used PBS instead of primary antibody, followed by Goat Anti-Mouse IgG H&L (Alexa Fluor^® 488) (Goat Anti-Mouse IgG H&L (Alexa Fluor® 488) ab150113) secondary antibody at 1/1000 dilution.

  Western blot - Anti-CD68 antibody [KP1] - BSA and Azide free (ab233172)

  This data was developed using the same antibody clone in a different buffer formulation (Anti-CD68 antibody [KP1] ab955).
  
  Blocking anf diluting buffer and concentraion: 5% NFDM /TBST
  
  Exposure time: Lane1: 60 seconds; Lane2: 5 seconds; Lane3: 180 seconds; Lane4: 7 seconds
  
  Anti-CD68 antibody [RM1031] ab303565 works better than Anti-CD68 antibody [KP1] ab955 in western blot testing.
  
  We suggest optimizing experimental protocols (increasing lysate amount, using lower dilution or higher sensitivity ECL substrate) to improve results when using Anti-CD68 antibody [KP1] ab955 in western blot.

  Lanes 1 and 3: Western blot - Anti-CD68 antibody [KP1] (Anti-CD68 antibody [KP1] ab955) at 1/1000 dilution

  Lanes 2 and 4: Western blot - Anti-CD68 antibody [RM1031] (Anti-CD68 antibody [RM1031] ab303565) at 1/1000 dilution

  Lanes 1 - 2: Human spleen tissue lysate at 20 µg

  Lanes 3 - 4: THP-1 (Human monocytic leukemia monocyte) whole cell lysate at 20 µg

  Secondary

  All lanes: Goat Anti-Rabbit IgG (HRP) with minimal cross-reactivity with human IgG at 1/2000 dilution

  Predicted band size: 37 kDa

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD68 antibody [KP1] - BSA and Azide free (ab233172)

  This data was produced using the same antibody clone but in a different formulation containing PBS, sodium azide, glycerol and BSA (Anti-CD68 antibody [KP1] ab955).

  Immunohistochemical analysis of formalin fixed paraffin embedded human liver labelling CD68 with Anti-CD68 antibody [KP1] ab955 at a concentration of 0.1 µg/ml. The immunostaining was performed on a Ventana DISCOVERY ULTRA (Roche Tissue Diagnostics) instrument with a OptiView DAB IHC Detection Kit. Heat mediated antigen retrieval was performed with DISCOVERY cell conditioning solution (CC1) 100°C, pH8.5 for 32mins.

  Anti-CD68 antibody [KP1] ab955 Anti-CD68 antibody [KP1] was incubated for 16mins at 37°C. Sections were counterstained with Hematoxylin II. Image inset shows absence of staining in secondary antibody only control.
