You will receive 1 vial of lysate (100ug), 1 vial of empty vector negative control (100ug), and 1 vial of 2xSDS sample buffer (250ul). Each vial of cell lysate contains 100ug of total protein (at 1 mg/ml). The 2xSDS Sample Buffer consists of 4% SDS, 125mM Tris-HCl pH6.8, 10% Glycerol, 0.002% Bromophenol blue, 100mM DTT.

Product Specifications

Application Notes

This product is intended for use as a positive control in Western Blot. Overexpression of the target protein was confirmed using an antibody to DDK (FLAG) epitope tag (NBP1-71705) present on the protein construct.

Each vial of cell lysate contains 100ug of total protein which should be sufficient for 20-50 reactions. Depending on over-expression level, antibody affinity and detection system, some lysates can go as low as 0.1 ug per load. We recommend starting with 5ug of cell lysate. Add an equal amount of cell lysate and 2X SDS Sample buffer and boil the SDS samples for 10 minutes before loading.

TMW

42 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background: alpha-Smooth Muscle Actin

Actin proteins are highly conserved in eukaryotic cells and are involved in cell motility, structure and integrity. Actin and myosin are involved in a myriad of cellular processes including locomotion, secretion, cytoplasmic streaming, phagocytosis and cytokinesis. Actin filaments, along with microtubules, comprise a major component of the cytoskeleton and play essential roles in regulating cell shape and movement. Actin has been found to be expressed in at least six isoforms, each encoded by a separate gene and expressed in a developmentally regulated and tissue-specific manner. Alpha, beta and gamma actin isoforms have been identified. Alpha actins are a major constituent of the contractile apparatus, whereas beta and gamma actins are involved in the regulation of cell motility.

ACTA2 encodes alpha Smooth Muscle Actin and is also known as alpha-actin, alpha-actin-2, aortic smooth muscle or alpha smooth muscle actin (alpha-SMA, SMactin, alpha-SM-actin, ASMA). Alpha Smooth Muscle Actin is frequently used as a marker of smooth muscle differentiation and has a theoretical molecular weight of 42 kDa. Smooth muscle alpha actin is one of a few genes whose expression is predominantly expressed in vascular smooth muscle cells that is used to study myofibroblasts and fibrosis (1). Excessive accumulation of alpha smooth muscle actin-positive (ACTA2+) activated myofibroblasts is observed in Idiopathic pulmonary fibrosis (2). Expression of smooth muscle alpha actin is regulated by cell proliferation and is altered in pathological conditions including atherosclerosis and is common in metastatic cancers (1,3).

Product Specific Notices for alpha-Smooth Muscle Actin Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Lysates are guaranteed for 6 months from date of receipt.
