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.

Anti-Biotin (D5A7) Rabbit mAb recognizes biotin attached to proteins, peptides, oligonucleotides, or solid matrices.
Monoclonal antibody is produced by immunizing animals with a biotinylated protein.
Biotin is a water-soluble B complex vitamin (vitamin H or B7) that serves as a coenzyme in various metabolic functions. It transfers carbon dioxide for five carboxylase enzymes and is involved in the TCA cycle and gluconeogenesis. In addition, all cells require biotin for cell proliferation, production of fatty acids, and metabolism of fats and amino acids (1). Biotin recycling and attachment to histone proteins is catalyzed by an enzyme named biotinidase. Histone biotinylation is involved in regulating telomere attrition and cellular senescence. Biotinidase deficiency is a rare genetic disorder that can cause neurological and cutaneous symptoms if left untreated (2). Biotin has a high affinity for its natural ligand, avidin. The complex and irregular structure of the biotin-binding site makes it highly optimized for biotin binding and confers great specificity to the avidin-biotin complexes (3). This remarkable affinity has been exploited for numerous immunoassays including ELISA, Flow Cytometry, Immunofluorescence, In Situ Hybridization, Affinity Chromatography, and Immunohistochemistry. Anti-Biotin (D5A7) Rabbit mAb can be used as an alternative to avidins in order to minimize background and maximize signal intensity.
