Allergin 1 Protein, Human, Recombinant (His Tag)

MILR1 (Mast Cell Immunoglobulin Like Receptor 1, also known as MCA32) is a Protein Coding gene. It is broadly expressed in the appendix, lymph node, and other tissues. Cell surface immunoreceptor MILR1 has been shown to suppress immunoglobulin E (IgE) -mediated, mast cell-dependent responses in both mice and humans. The C allele of rs6504230 was associated with increased expression of MILR1, which was following the results of expression quantitative trait loci analysis using human leukocytes. The rs6504230 polymorphism affects MILR1 expression levels in humans, leading to a susceptibility to producing specific IgE antibodies against common allergens. Diseases associated with MILR1 include Mitochondrial Dna Depletion Syndrome 16 and Autosomal Dominant Progressive External Ophthalmoplegia.

At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
