For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
NOTE: Please refer to primary antibody datasheet or product webpage for recommended antibody dilution.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
Load 20 µl onto SDS-PAGE gel (10 cm x 10 cm).
NOTE: Volumes are for 10 cm x 10 cm (100 cm2) of membrane; for different sized membranes, adjust volumes accordingly.
* Avoid repeated exposure to skin.

Reprobing of an existing membrane is a convenient means to immunoblot for multiple proteins independently when only a limited amount of sample is available. It should be noted that for the best possible results a fresh blot is always recommended. Reprobing can be a valuable method but with each reprobing of a blot there is potential for increased background signal. Additionally, it is recommended that you verify the removal of the first antibody complex prior to reprobing so that signal attributed to binding of the new antibody is not leftover signal from the first immunoblotting experiment. This can be done by re-exposing the blot to ECL reagents and making sure there is no signal prior to adding the next primary antibody.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.

Protocol Id: 263
Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.
CMTM6 Antibody recognizes endogenous levels of total CMTM6 protein. This antibody does not cross-react with CMTM4 protein.
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala176 of human CMTM6 protein. Antibodies are purified by protein A and peptide affinity chromatography.
CKLF-like MARVEL transmembrane domain-containing protein 6 (CMTM6) is a member of the chemokine-like factor (CKLF)-like MARVEL transmembrane domain-containing family (1). CMTM6 stabilizes plasma membrane expression of PD-L1, an immune inhibitory ligand critical for immune tolerance to self and anti-tumor immunity (2,3). CMTM6 associates with PD-L1 at recycling endosomes, where it protects PD-L1 from being targeted for lysosomal degradation by preventing STUB1-mediated PD-L1 ubiquitination (2,3). CMTM6 may stabilize PD-L1 expression on antigen presenting cells and potentiate inhibitory signaling by PD-1 on T cells, triggering T cell inhibition and exhaustion. CMTM6 has also been shown to interact with with CD58, ARG1, ENO1, and TMPO (2). Due to the role of CMTM6 in regulating the immune system, it is being investigated as an immunotherapeutic target for the treatment of cancer.
