Alternative names:

hQSOX;Quiescin Q6

Description:

Recombinant human QSOX1 protein with C-terminal 6×His tag

Background:

This gene encodes a protein that contains domains of thioredoxin and ERV1, members of two long-standing gene families. The gene expression is induced as fibroblasts begin to exit the proliferative cycle and enter quiescence, suggesting that this gene plays an important role in growth regulation. Two transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Molecular characterization:

QSOX1(Ala30-Ser706) 6×His tag

Molecular weight:

The protein has a predicted molecular mass of 75.9 kDa after removal of the signal peptide. The apparent molecular mass of QSOX1-His is approximately 70-100 kDa due to glycosylation.

Tag:

C-6×His Tag

Expression host:

HEK293

Target:

QSOX1

Purity:

The purity of the protein is greater than 85% as determined by SDS-PAGE and Coomassie blue staining.

Formulation / Reconstitution:

Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8% trehalose is added as protectants before lyophilization. Please see Certificate of Analysis for specific instructions of reconstitution.

Storage:

Store at -20°C to -80°C for 12 months in lyophilized form. After reconstitution, if not intended for use within a month, aliquot and store at -80°C (Avoid repeated freezing and thawing). Lyophilized proteins are shipped at ambient temperature.
