Western blot analysis of extracts from various cell lines using GIMAP5 Antibody.
Learn more about how we get our imagesFor 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: Loading of prestained molecular weight markers (#13953, 10 µl/lane) to verify electrotransfer and biotinylated protein ladder (#7727, 10 µl/lane) to determine molecular weights are recommended.
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
This protocol is intended for immunoprecipitation of native proteins for analysis by western immunoblot or kinase activity utilizing magnetic separation.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
10X Cell Lysis Buffer: (#9803) To prepare 10 ml of 1X cell lysis buffer, add 1 ml cell lysis buffer to 9 ml dH2O, mix.
NOTE: Add 1 mM PMSF (#8553) immediately prior to use.
A cell lysate pre-clearing step is highly recommended to reduce non-specific protein binding to the Protein A Magnetic beads. Pre-clear enough lysate for test samples and isotype controls.
IMPORTANT: Pre-wash #73778 magnetic beads just prior to use:
Carefully remove the buffer once the solution is clear. Add 500 μl of 1X cell lysis buffer to the magnetic bead pellet, briefly vortex to wash the beads. Place tube back in magnetic separation rack. Remove buffer once solution is clear. Repeat washing step once more.
IMPORTANT: The optimal lysate concentration will depend on the expression level of the protein of interest. A starting concentration between 250 μg/ml-1.0 mg/ml is recommended.
IMPORTANT: Appropriate isotype controls are highly recommended in order to show specific binding in your primary antibody immunoprecipitation. Use Normal Rabbit IgG #2729 for rabbit polyclonal primary antibodies, Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 for rabbit monoclonal primary antibodies, and Mouse (G3A1) mAb IgG1 Isotype Control #5415 for mouse monoclonal primary antibodies. Isotype controls should be concentration matched and run alongside the primary antibody samples
Proceed to one of the following specific set of steps.
NOTE: To minimize masking caused by denatured IgG heavy chains (~50 kDa), we recommend using Mouse Anti-Rabbit IgG (Light-Chain Specific) (D4W3E) mAb (#45262) or Mouse Anti-Rabbit IgG (Conformation Specific) (L27A9) mAb (#3678) (or HRP conjugate #5127). To minimize masking caused by denatured IgG light chains (~25 kDa), we recommend using Mouse Anti-Rabbit IgG (Conformation Specific) (L27A9) mAb (#3678) (or HRP conjugate #5127).

GIMAP5 Antibody recognizes endogenous levels of total GIMAP5 protein. This antibody also recognizes proteins of unknown origin at 12 kDa and 50 kDa.
Human
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human GIMAP5 protein. Antibodies are purified by protein A and peptide affinity chromatography.
GTPase immune-associated proteins (GIMAP), also known as immune-associated nucleotide-binding (IAN) proteins, are evolutionarily conserved GTP-binding proteins involved in lymphocyte development, inflammation, and autoimmune diseases (reviewed in 1,2). Human GTPase IMAP family member 5 (GIMAP5, hIan5) is the homolog of the rat Ian4 protein that is mutated in severe cases of T-cell lymphopenia and insulin-dependent diabetes in Biobreeding diabetes-prone (BB-DP) rats (3,4). GIMAP5 protein is preferentially expressed in CD4- and CD8-positive T-cells as well as B-cell lymphomas (4). Research studies using GIMAP5-deficient mice show that GIMAP5 protein is critical for survival of peripheral T-cells, hematopoietic stem cells, and progenitor cells (5-7). Additional studies indicate that GIMAP5 deficiency leads to a loss of immunological tolerance (8). Polymorphisms in the human GIMAP5 gene are associated with systemic lupus erythematosus and type I diabetes (9-11). Potential mechanisms for GIMAP5 control of cell survival include regulation of Bcl-2 family proteins, mitochondrial integrity, lysosomal function, and calcium regulation (7, 12-15).
