Product Overview

Tag	His
Host Species	Human
Accession	NP_114434.3
Synonym	KREMEN, KRM1
Background	The cell surface molecule KREMEN1 is an entry receptor for coxsackievirus A1 (CV-A1).Whereas loss of KREMEN1 renders cells resistant to CV-A1 infection, KREMEN1 overexpression enhances CV-A1 binding to the cell surface and increases susceptibility to infection, indicating that KREMEN1 is a rate-limiting factor for CV-A1 infection.KREMEN1 is also essential for infection by a phylogenetic and pathogenic related group of Human type A Enteroviruses (EV-As).
Description	A DNA sequence encoding the human KREMEN1 (NP_114434.3) (Met1-Thr394) was expressed with a His tag at the C-terminus.
Source	HEK293
Predicted N Terminal	Ala 20
AA Sequence	Met1-Thr394
Molecular Weight	The recombinant human KREMEN1 consists of 386 a.a. and predicts a molecular mass of 42.6 KDa. It migrates as an approximately 56.3 KDa band in SDS-PAGE under reducing conditions.
Purity	>95% as determined by SDS-PAGE
Endotoxin	< 1.0 EU per μg of the protein as determined by the LAL method

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.
