Product Overview

Tag	Fc
Host Species	Human
Accession	AAK91503.1
Synonym	RAET1L, ULBP6
Background	ULBP6/RAET1L, is a polymorphic locus that expresses a functional transcript. ULBP6 had a more restricted expression profile in cell lines and primary human tissues than other NKG2D ligands, but expression was detected in several human papillomavirus-positive cervical carcinoma cell lines and was inducible on infection with human CMV. Expression of ULBP6 on target cells induced a significant increase in NK-cell killing.
Description	A DNA sequence encoding the human RAET1L (AAK91503.1) (Met1-Ser217) was expressed with the Fc region of human IgG1 at the C-terminus.
Source	HEK293
Predicted N Terminal	Arg 26
AA Sequence	Met1-Ser217
Molecular Weight	The recombinant human RAET1L consists 430 a.a. and predicts a molecular mass of 48.5 kDa.
Purity	>90% as determined by SDS-PAGE.
Endotoxin	< 1.0 EU per μg protein as determined by the LAL method.
Bioactivity	Measured by its binding ability in a functional ELISA.Immobilized human His-NKG2D(78-216) at 10 ug/ml (100 ul/well) can bind RAET1L-Fc, The EC50 of RAET1L-Fc is 13-30ng/ml.

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.
