Target Beta-Actin Target background β-actin (gene name ACTB) is one of six different actin isoforms which have been identified in humans. This is one of the two non-muscle cytoskeletal actins. Actins are highly conserved proteins that are involved in cell motility, structure and integrity. The β-actin gene is often stably and constitutively expressed at high levels in most tissues and cells. Proteins such as β-actin, involved in maintenance of basic cellular function, are often referred to as housekeeping proteins. Housekeeping proteins are frequently used as loading controls for western blots and protein normalization. Specificity The antibody recognizes native and denatured forms of β-Actin (~42kDa) Clone ID BA3R Isotype IgG2b Preservative None Format Purified with protein G, stored in PBS pH 7.4 and lyophilized. Recommend starting dilution If reconstituted with deionized water in 100 µl: WB 1:1000-3,000, IHC 1:500-2,000. Optimal dilution has to be determined by the user. Limitations Research Use Only Storage Lyophilized antibodies can be kept at 4ºC for up to 3 months and should be kept at -20ºC for long-term storage (2 years). To avoid freeze-thaw cycles, reconstituted antibodies should be aliquoted before freezing for long-term (1 year) storage (-80ºC) or kept at 4ºC for short-term usage (2 months). For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made with the assay buffer. After the maximum long-term storage period (2 years lyophilized or 1 year reconstituted) antibodies should be tested in your assay with a standard sample to verify if you have noticed any decrease in their efficacy. To limit antibody loss or degradation, BSA (final concentration 1%) and sodium azide (final concentration 0.02%) can be added to the suggested first dilution. It is important to first verify if those preservatives are compatible with your assay.
