Recombinant Human EPHA4 protein, His & GST-tagged

Specification :
| Description : This gene belongs to the ephrin receptor subfamily of the protein-tyrosine kinase family. EPH and EPH-related receptors have been implicated in mediating developmental events, particularly in the nervous system. Receptors in the EPH subfamily typically have a single kinase domain and an extracellular region containing a Cys-rich domain and 2 fibronectin type III repeats. The ephrin receptors are divided into 2 groups based on the similarity of their extracellular domain sequences and their affinities for binding ephrin-A and ephrin-B ligands. Multiple transcript variants encoding different isoforms have been found for this gene. | Source : E. coli | Species : Human | Tag : His & GST | Form : Freeze-dried powder | Molecular Mass : Predicted Molecular Mass: 59.7kDa. | Protein length : Ile621~Ile882 (Accession # P54764) | Endotoxin : | Purity : >95% | Characteristic : The isoelectric point is 8.2. | Applications : SDS-PAGE; WB; ELISA; IP. | Stability : The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37°C for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition. | Storage : Avoid repeated freeze/thaw cycles. Store at 2-8°C for one month. Aliquot and store at -80°C for 12 months. | Storage buffer : Supplied as lyophilized form in PBS, pH7.4, containing 5% trehalose, 0.01% sarcosyl. | Reconstitution : Reconstitute in sterile PBS, pH7.2-pH7.4.
