Antigen

Cell type Class: Blood
Cell type: Macrophages
MeSH Description: The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

library_construction_protocol: 20 000 sorted TAMs were collected in 1mL of PBS + 3% FBS at 4°C.Cells were centrifuged, then cell pellets were resuspended in 50 μL of lysis buffer (Tris HCl 10 mM, NaCl 10 mM, MgCl2 3 mM, Igepal 0,1%) and centrifuged (500 g) for 10 minutes at 4°C. Supernatant was discarded and nuclei were resuspended in 50 μL of reaction buffer (Tn5 transposase 2,5 μL, TD buffer 22,5 μL and 25 μL H2O – Nextera DNA sample preparation kit, Illumina). Tagmentation was performed for 30 minutes at 37°C. DNA was purified using the MinElute purification kit (QIAGEN). Purified DNA was amplified and indexed by PCR using NEBNext High-Fidelity 2× PCR Master Mix (New England Biolabs) with 10-12 cycles. Llibraries were purified using MinElute PCR Purification Kit (Qiagen) and quality controlled using a Bioanalyzer High-Sensitivity DNA Analysis kit (Agilent).
