• Preparation and Storage: Avoid repeated freeze/thaw cycles. Store at 2-8 degree C for one month. Aliquot and store at -80 degree C for 12 months.; Stability Test: The thermal stability is described by the loss rate of the targetprotein. The loss rate was determined by accelerated thermal degradation test,that is, incubate the protein at 37 degree C for 48h, and no obvious degradation andprecipitation were observed. (Referring from China Biological Products Standard,which was calculated by the Arrhenius equation.) The loss of this protein is lessthan 5% within the expiration date under appropriate storage condition.

NCBI Description

This gene encodes a telomere specific protein which is a component of the telomere nucleoprotein complex. This protein is present at telomeres throughout the cell cycle and functions as an inhibitor of telomerase, acting in cis to limit the elongation of individual chromosome ends. The protein structure contains a C-terminal Myb motif, a dimerization domain near its N-terminus and an acidic N-terminus. Two transcripts of this gene are alternatively spliced products.

Uniprot Description

TRF1: a telomeric repeat binding factor. Binds the telomeric double-stranded TTAGGG repeat and negatively regulates telomere length. Colocalizes with telomeric DNA in interphase and metaphase cells and is located at chromosome ends during metaphase. Involved in the regulation of the mitotic spindle. Expression is tightly regulated during the cell cycle; levels are low in G1 and S phase and increase during G2 phase and mitosis. Two splice variant isoforms have been described.
