Recombinant Human ESR1 protein, His-tagged

Cat.No.: ESR1-28402TH
Product Overview: Recombinant Human ESR1(Ser178~Met438) fused with His tag at N-terminal was expressed in E. coli.
Description: This gene encodes an estrogen receptor, a ligand-activated transcription factor composed of several domains important for hormone binding, DNA binding, and activation of transcription. The protein localizes to the nucleus where it may form a homodimer or a heterodimer with estrogen receptor 2. Estrogen and its receptors are essential for sexual development and reproductive function, but also play a role in other tissues such as bone. Estrogen receptors are also involved in pathological processes including breast cancer, endometrial cancer, and osteoporosis. Alternative promoter usage and alternative splicing result in dozens of transcript variants, but the full-length nature of many of these variants has not been determined.
Source: E. coli
Species: Human
Tag: His
Form: PBS, pH7.4, containing 0.01% SKL, 1mM DTT, 5% Trehalose and Proclin300.
Molecular Mass: 33.4 kDa
Protein length: Ser178~Met438
Endotoxin: <1.0EU per 1µg (determined by the LAL method)
Purity: > 90%
Applications: SDS-PAGE; WB; ELISA; IP
Storage: Avoid repeated freeze/thaw cycles. Store at 2-8 centigrade for one month. Aliquot and store at -80 centigrade for 12 months.
Preservative: 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 centigrade 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.
Reconstitution: Reconstitute in PBS or others.
