Check if the same lab product or an alternative is used in the 5 most similar protocols
Cryosections of 7 μm were fixed and stained immunohistochemically as previously described (Allen et al., 2004 (link)) with the following antibodies: PE-conjugated anti-IgD (11–26c.2a; Biolegend), biotin-conjugated anti-GL7 (GL7, Biolegend), and FITC-conjugated 33D1 antibody (33D1, Biolegend). Images were captured with a Zeiss AxioOberver Z1 inverted microscope. For multiphoton imaging, CD11cYFP mice were injected with PKH26 (Sigma-Aldrich)-labeled Cd47−/− RBCs 20 mins before the spleen was harvested and sectioned longitudinally with a vibratome (Leica). The cut spleen was perfused with RPMI1640 medium (Life Technologies) plus 10mM HEPES and 95% CO2 5% O2. The cut spleen was imaged with a 7MP two-photon microscope (Carl Zeiss) equipped with a Chameleon laser (Coherent). Excitation wavelengths were 940nm for YFP and 800nm for PKH26. The z-stack was 21μm thick with 3μm intervals. The image was acquired with ZEN2012 (Carl Zeiss) and the three dimensional movie was made with Imaris 7.4.2 x64 (Bitplane).

Cryosections of 10 µm were fixed by acetone for 10 min, dried for 1 h, and stained with goat anti-IgD, FITC-conjugated anti-Marco (Bio-Rad), FITC-conjugated anti-CD169 (BioLegend), biotin-conjugated 33D1 (BioLegend), streptavidin-AF647 (Thermo Fisher Scientific), and AMCA-conjugated donkey anti-goat IgG (H+L; Jackson Immunoresearch). Primary antibody incubation was performed overnight at 4°C, followed by secondary staining for 3 h at room temperature. For staining of 33D1 (anti-DCIR2), the tyramide amplification kit was used (TSA Biotin System) according to the manual. Images were captured with a Zeiss AxioOberver Z1 inverted microscope and stitched by Zen software.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
