CD18 antibody | YFC118.3
R-phycoerythrin conjugated Rat anti Human CD18 antibody, clone YFC118.3 (MCA503PE) used for flow cytometry
Image caption:
The levels of CD11b and CD18 fall dramatically following incubation with Leishmania under serum dependent (SD) culture conditions. Peritoneal macrophages were selected based on forward- versus side-scatter parameters as described in Materials and Methods and Figure 1 using flow cytometry. A) Isotype control with macrophages showing delineation of the M1 marker based on the negative population. B and C represent expression of CD18 (B) or CD11b (C) before incubation with Leishmania. D and E represent expression of CD18 (D) or CD11b (E) after association with Leishmania in a SD assay. In all cases the percent positive cells within the M1 marker are identified. This Figure is a representative diagram of 4 experiments with similar findings.

Subretinal MPs accumulate on the retinal pigment epithelium in AMD
A–D Confocal microscopy of IBA‐1 (green staining) immunohistochemistry of RPE flatmounts (RPE autofluorescence visible as orange due to its autofluorescence in the red and green channel) from a healthy donor (A), a geographic atrophy lesion (B), and large drusen (C and D). (A, B, D): orthogonal Z‐stack projection; (C): oblique Z‐stack projection and dissecting microscope appearance of postmortem large drusen after removal of the overlaying retina (inset). E–G Double‐labeling on the subretinal side of the retina (to avoid masking by RPE autofluorescence) of IBA‐1+ (E, green fluorescence) and CD18 (F, red fluorescence; G, merge). H. Orthogonal and lateral Z‐stack of a subretinal IBA‐1+ (green fluorescence) MPs adjacent to the RPE (orange autofluorescence) in the vicinity of a large drusen.
Data information: Controls omitting the primary antibody showed no staining apart from the autofluorescence. AZ: atrophic zone; LD: large drusen. Scale bar: 50 μm (A–D); 10 μm (E–H).

LFA-1 activation analyses by Flow Cytometry. (A) Profiles of CD11a, CD18 activation epitope (CD18act, representing “high affinity” conformation) and CD18 (CD18tot) expression by Teff and Treg#1 cells pre-incubated or not with indicated antibodies. Anti-CD28 and anti-CTLA-4 were used at 10 µg/ml. (B) Histograms of Mean Fluorescent Intensity (MFI) of CD11a, CD18act and CD18tot expressed on Teff and Treg#1 cells. Ratio CD18act MFI: CD18tot was established to analyze LFA-1 high affinity conformation in indicated conditions. Data are representative of more than three different experiments. Filled gray, negative control; Red line, Teff and Treg cells alone; Green line, cells with APC; Blue line, cells with APC and anti-CD28; and Black line: cells with APC, anti-CD28 and anti-CTLA-4.

Rat anti Human CD18 antibody, clone YFC118.3 was clustered at the Fourth International Workshop on Leucocyte Differentiation Antigen (code number N221) as recognizing the CD18 antigen.
The CD18 antigen is an integral membrane glycoprotein of ~95 kDa, known as the beta chain, of the LFA-1 complex. The CD18 antigen is non-covalently linked to CD11a, b, c molecules. The CD18 molecule is the receptor for ICAM-1 and is thus important for cell adhesion.
The main cellular reactivity of Rat anti Human CD18 antibody, clone YFC118.3 is a strong reactivity with leucocytes (platelets negative).
