Product Overview

Tag Fc
Host Species Mouse
Accession NP_001028607.1
Synonym Allergin-1, Gm885, Mca32
Background Cell surface immunoreceptor MILR1 (mast cell immunoglobulin-like receptor 1; synonyms, Allergin-1) has been shown to suppress immunoglobulin E (IgE)-mediated, mast cell-dependent responses in both mice and humans.The C allele of rs65423 was associated with increased expression of MILR1, which was in accordance with the results of expression quantitative trait loci analysis using human leukocytes. The rs65423 polymorphism affects MILR1 expression levels in humans, leading to a susceptibility to producing specific IgE antibodies against common allergens.
Description A DNA sequence encoding the mouse MILR1 (NP_001028607.1) (Met1-Ser150) was expressed with the Fc region of human IgG1 at the C-terminus.
Source HEK293
Predicted N Terminal Ile 34
AA Sequence Met1-Ser150
Molecular Weight The recombinant mouse MILR1 consists of 355 a.a. and predicts a molecular mass of 39.8 kDa.
Purity >95% as determined by SDS-PAGE.
Endotoxin < 1.0 EU per μg protein as determined by the LAL method.
Bioactivity Please contact us for detailed information
Formulation Lyophilized from sterile PBS, pH 7.4..
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.

Target Details

Target Function Immunoglobulin-like receptor which plays an inhibitory role in degranulation of mast cells. Negatively regulates IgE-mediated mast cell activation and suppresses the type I immediate hypersensitivity reaction.
Subcellular Location Cell membrane; Single-pass type I membrane protein.; [Isoform 2]: Secreted.
Database References
Tissue Specificity Expressed in myeloid cells (dendritic cells, macrophages and neutrophils but not in T-cells, B-cells or natural killer cells) and mast cells (at protein level).

Gene Functions References

  1. The results suggest that Allergin-1 on skin MCs suppresses TLR2-induced dermatitis. PMID: 27932517
  2. It is a immunoglobulin-like receptor which regulates the activation of mast cell.(review) PMID: 24552759

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.
