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.

Integrin β2 (D4N5Z) Rabbit mAb recognizes endogenous levels of total Integrin β2 protein.
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu49 of human Integrin β2 protein.
Integrins are transmembrane glycoproteins that form heterodimers consisting of one α and one β subunit. Integrin dimers act as receptors for extracellular matrix proteins and cell-surface ligands. Integrin signaling to (inside-out) and from (outside-in) extracellular molecules regulates multiple cellular processes, such as development, wound healing, immune response, invasion, metastasis, and angiogenesis (1,2). Integrin β2 (CD18) is the β subunit of the leukocyte-specific integrin family. Leukocyte integrins include Integrin β2 (CD18)/αL (CD11a) (LFA-1, lymphocyte function associated antigen 1), Integrin β2 (CD18)/αM (CD11b) (Mac-1), Integrin β2(CD18)/αX (CD11c), and Integrin β2 (CD18)/αD (CD11d). These integrins bind to immunoglobulin superfamily members, such as ICAM-1 and VCAM-1 on endothelial cells, to mediate firm adhesion and transendothelial migration of leukocytes (3). Integrin β2 (CD18) deficiency results in LAD (leukocyte adhesion deficiency), a disease characterized by impairment of leukocyte recruitment resulting in inability to fight infection (4).
