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 b-actin (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.
Applications:
Suitable for use in ELISA and Western Blot. Other applications not tested.
Recommended Dilutions:
ELISA: 1:5000-1:10,000
Western Blot: 1:1000-1:5000
Optimal dilutions to be determined by the researcher.
Storage and Stability:
Lyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with sterile PBS. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Reconstituted product is stable for 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Labeled with horseradish peroxidase (HRP). Sodium azide is a potent inhibitor of peroxidase and should not be added to HRP conjugates. HRP conjugates are sensitive to light.
