Specifications

Actin and myosin are the two major cytoskeleton proteins implicated in cellular movement, secretion, phagocytosis, and kinesis. Actin is one of the most conserved cellular protein. At least 6 actin isoforms have been identified by protein sequence analyses. Four actin isoforms represent the differentiation markers of muscle tissues. There are three a-actins: a-skeletal, a-cardiac, and a-smooth muscle), one bactin (b-non-muscle), and two g-actins (g-smooth muscle and g-non-muscle). Actin isoform are >90% conserved, except in the N-terminal 18-aa (50-60% homology). Beta-actin protein and mRNA levels are often used as a reference for comparing changes in cellular protein/mRNA levels by Western or Northern blots.

Catalog #A0760-47B
ApplicationsSuitable for use in Western Blot. Other applications not tested.
Recommended DilutionWestern Blot: load 10ul/lane.
Note: SDS may crystallize in cold conditions. It should redissolve by warming before taking it from the stock. It should be heated once prior to loading on gels. If the product has been stored for several weeks, then it may be preferable to add 5ul of fresh 2x sample buffer per 10 ul of the A0760-47B solution prior to heating and loading on gels. This preparation is not biologically active.
Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage, aliquot and store at -20°C. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
PurityPurified by affinity chromatography to >95% purity.
FormSupplied as a lyophilized powder from PBS, 0.05% sodium azide.
Important NoteThis product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological.
