Mouse cd11b antibody

Manufactured by BioLegend

The Mouse CD11b Antibody is a monoclonal antibody that binds to the CD11b protein, also known as the integrin alpha M chain or Mac-1 alpha chain. CD11b is expressed on the surface of various immune cells, including monocytes, macrophages, and granulocytes. This antibody can be used to identify and study these cell types in mouse models and research applications.

Cytosolic fraction was isolated as previously described (Vanaja et al., 2016 (link)). Spleens were collected 5 h post-LPS injection and crushed through 100 μm nylon-mesh strainer. RBCs were lysed using ACK lysis buffer (Gibco). Splenocytes were incubated with Fc block, stained with mouse CD11b antibody (Clone M1/70; BioLegend catalog no. 101212) and sorted on BD FACS Aria II. Sorted CD11b + cells were resuspended in 0.001% digitonin buffer for 8 min and supernatant containing the cytosolic content was collected. Cytosolic LPS was quantified using the Limulus Amebocyte Lysate (LAL) assay (Associates of Cape Cod) according to the manufacturer’s instructions. HEK293 cells expressing hTLR4 (Invivogen) were cultured with HEK-Blue Detection and HEK-Blue Selection (Invivogen) in a 96-well plate according to the manufacturer’s protocol. Cytosol from CD11b+ splenocytes was added to the cell culture medium and SEAP activity was assessed by measuring absorbance at 620–655 nm.

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.
