Recombinant Human WT1 protein, His & GST-tagged

• Cat.No.: WT1-1402H
• Product Overview: Recombinant Human WT1 aa. (Leu310~Leu449 fused with N-terminal His & GST tag was produced in E. coli cells.

Specification

• Description: This gene encodes a transcription factor that contains four zinc-finger motifs at the C-terminus and a proline/glutamine-rich DNA-binding domain at the N-terminus. It has an essential role in the normal development of the urogenital system, and it is mutated in a small subset of patients with Wilms tumor. This gene exhibits complex tissue-specific and polymorphic imprinting pattern, with biallelic, and monoallelic expression from the maternal and paternal alleles in different tissues. Multiple transcript variants have been described. In several variants, there is evidence for the use of a non-AUG (CUG) translation initiation codon upstream of, and in-frame with the first AUG. Authors of PMID:7926762 also provide evidence that WT1 mRNA undergoes RNA editing in human and rat, and that this process is tissue-restricted and developmentally regulated.
• Source: E. coli
• Species: Human
• Tag: His&GST
• Form: Freeze-dried powder
• Molecular Mass: 47kDa as determined by SDS-PAGE reducing conditions.
• Protein length: Leu310~Leu449
• Endotoxin: <1.0EU per 1µg (determined by the LAL method)
• Purity: >90%
• Characteristic: The isoelectric point is 10.3.
• Applications: Positive Control; Immunogen; SDS-PAGE; WB.
• Stability: The thermal stability is described by the loss rate. 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. The loss rate is less than 5% within the expiration date under appropriate storage condition.
