		Technical Data
T5010-11J1	TXNDC4 (Endoplasmic Reticulum Resident Protein 44, ER Protein 44, ERp44, Thioredoxin Domain-containing Protein 4, KIAA0573, ERP44, UNQ532/PRO1075)

Description:
Mediates thiol-dependent retention in the early secretory pathway, forming mixed disulfides with substrate proteins through its conserved CRFS motif. Inhibits the calcium channel activity of ITPR1. May have a role in the control of oxidative protein folding in the endoplasmic reticulum. Required to retain ERO1L and ERO1LB in the endoplasmic reticulum.

Applications:
Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
ELISA: 1:32,000
Western Blot: 0.2-0.6ug/ml, observed in lysates of cell line K562 on ~47kD bands
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
