T Plastin/PLS3 Protein, Human, Recombinant (His Tag)

PLS3, also known as plastin 3, belongs to the plastin family. Members of this family are actin-binding proteins that are conserved throughout eukaryote evolution and expressed in most tissues of higher eukaryotes. There are two ubiquitous plastin isoforms in humans: L and T. The L isoform is expressed only in hemopoietic cell lineages, while the T isoform has been found in all other normal cells of solid tissues that have replicative potential (fibroblasts, endothelial cells, epithelial cells, melanocytes, etc.) . PLS3 contains 2 actin-binding domains, 4 CH (calponin-homology) domains and 2 EF-hand domains. It is expressed in a variety of organs, including muscle, brain, uterus and esophagus.

At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

Lyophilized from sterile PBS, 10% Glycerol, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

The recombinant human PLS3 consists of 289 amino acids and predicts a molecular mass of 32.2 KDa. It migrates as an approximately 30-34 KDa band in SDS-PAGE under reducing conditions.

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
