Rabbit anri IRE1p antibody recognizes the C-terminus of inositol-requiring kinase 1 precursor (IRE1p), a 108 kDa serine-threonine kinase/endoribonuclease also known as ERN1. It is an endoplasmic reticulum (ER) transmembrane protein, normally bound to the ER molecular chaperones GRP78 and GRP94. At times of ER stress, due to accumulation of unfolded proteins, IRE1p becomes dissociated from the chaperones, which allows it to activate the un-folded protein transcriptional response (UPR). In the mammalian genome, there are two homologs Ire1alpha and Ire1beta. Ire1alpha is expressed in all cells and tissues, Ire1beta expression is primarily restricted to intestinal epithelial cells.

Storage Information

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.
