Product Overview

Tag	His
Host Species	Human
Accession	AAH14475.1
Synonym	KIAP, LIVIN, ML-IAP, MLIAP, RNF50
Background	BIRC7, a new member of inhibitor of the apoptosis protein family, is expressed in fetal tissues and most solid tumors in humans. BIRC7/livin expression is a novel prognostic marker in adult acute leukemia. Livin/BIRC7 is a member of the inhibitors of apoptosis proteins family, which are involved in tumor development through the inhibition of caspases. Livin/BIRC7 is specifically over-expressed in ACC, suggesting that it might be involved in adrenocortical tumorigenesis and represent a new molecular marker of malignancy.
Description	A DNA sequence encoding the human BIRC7 (AAH14475.1) (Met1-Ser298) was expressed with a His tag at the C-terminus.
Source	E.coli
Predicted N Terminal	Met
AA Sequence	Met1-Ser298
Molecular Weight	The recombinant human BIRC7 consists of 304 a.a. and predicts a molecular mass of 33.6 kDa. It migrates as an approximately 35 kDa band in SDS-PAGE under reducing conditions.
Purity	>85% as determined by SDS-PAGE
Endotoxin	Please contact us for more information.
Bioactivity	Measured by its ability to reverse the inhibition of DEVD-AFC cleavage activity in cell extracts activated by addition of cytochrome c and dATP.The IC50 for this effect is typically 0.6-3.0 uM.
Formulation	Lyophilized from sterile 50 mM Tris, 200 mM NaCl, pH 8.0..
Stability	The recombinant proteins are stable for up to 1 year from date of receipt at -70°C.
Usage	For Research Use Only
Storage	Store the protein under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
