After dewaxing and hybration, the sectioned samples were blocked with 10% FBS. The sections were incubated with primary antibodies at 4°C overnight. The antibodies used were anti-CD7, anti-CD8, anti-CD14, anti-CD15, anti-CD18, anti-CD19 and anti-carcinoembryonic antigen (CEA) (Abcam, Cambridge, MA, USA). The sections were then incubated with Alexa Fluor 488-conjujated anti-mouse/anti-rabbit secondary antibodies (Cell Signaling Technology, Inc., Danvers, MA, USA), for 1 h at room temperature. Nuclei were stained with Hoechst 33342 (Invitrogen Life Technologies).

Immunofluorescent and Immunohistochemical Analysis of Endometrial/Decidual Tissues

Check if the same lab product or an alternative is used in the 5 most similar protocols
For immunofluorescent staining, paraffin slides of endometrial/decidual tissues were processed and incubated with primary antibodies, including anti-CD15 (Abcam, USA; 1:1000) and anti-H3Cit (ab5103, USA; 1:1000), before being stained with fluorescent secondary antibodies and DAPI. The images were acquired with a fluorescence microscope (Olympus, Japan), and the number of endometrial/decidual samples with Nets positive was counted. Meanwhile, the paraffin slides were processed and stained with PAD4 antibody (Affinity, USA; 1:200) before being stained with secondary antibodies and chromogen substrate for immunohistochemical staining.

The SGECs on coverslips were fixed in 4% paraformaldehyde for 10 min, permeabilized with 0.1% Triton X-100 (Sigma) for 20 min at room temperature. Subsequently, 10% FBS was used to block non-specific binding. The SGECs were then incubated with primary antibodies at 4°C overnight. The antibodies that were used were the following: anti-CD7, anti-CD8, anti-CD14, anti-CD15, anti-CD18, anti-CD19, anti-CEA and anti-LGR5 (Abcam). The cells were then incubated with Alexa Fluor 488-conjujated anti-mouse/anti-rabbit secondary antibodies (Cell Signaling Technology, Inc.) for 1 h at room temperature. Nuclei were stained with Hoechst 33342.

Multiparametric Immunofluorescence Analysis of Tumor Infiltrates

Check if the same lab product or an alternative is used in the 5 most similar protocols
Paraffin-embedded sections were de-paraffinized in xylene and rehydrated using alcohol. Citrate buffer were applied to retrieve antigen by incubating the sections by boiling for 10 min in the microwave. Before incubation with primary antibodies at room temperature for an hour, cells were fixed with 4% paraformaldehyde for 10 min and then rinsed with PBS twice and incubated 20 min with fluorescence-conjugated secondary antibodies. The nuclei staining was located with DAPI (Invitrogen) and coverslipped. Immunofluorescent images were first exported and quality by Akoya system. Tumor cryosections were stained with anti-CD3 (clone: D4V8L; cell signaling technical, Mouse), anti-CD8 (clone: D4W2Z; cell signaling technical, Mouse), anti-CD11b (clone: D6X1N; cell signaling technical, Human, Mouse), anti-Ly-6G (clone: E6Z1T; cell signaling technical, Mouse), anti-CD15 (clone: MC480, Human), and anti-CD33 (clone: EPR23051-101, Abcam, Human). Tissues were quantified with Mantra Quantitative Pathology Workstation.

Proteins (20 μg/lane) were fractionated by SDS-PAGE and electrotransferred onto polyvinylidene difluoride membranes. The blots were first incubated for 1 h in a blocking buffer consisting of 0.1% Tween-20 (Invitrogen Life Technologies) and 5% non-fat powdered milk, then incubated with a primary antibody at 4°C overnight. The antibodies that were used were as follows: anti-CD7, anti-CD8, anti-CD14, anti-CD15, anti-CD18, anti-CD19 (Abcam) and anti-β-actin (Cell Signaling Technology, Inc.). A horseradish peroxidase-conjugated, goat anti-mouse/anti-rabbit secondary antibody (Zhongshan Jinqiao Biotechnology Co., Ltd., Beijing, China) then was used and antigen-antibody complexes were detected by chemiluminescence using the BeyoECL Plus kit (BiYunTian Biotechnology Research Laboratory, Haimen, China).

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.
