MARCO Protein, Human, Recombinant (His)

Macrophage receptor with collagenous structure (MARCO) is the predominant scavenger receptor for recognition and binding of silica particles by alveolar macrophages (AM). MARCO contributes to normal cholesterol uptake in macrophages; therefore, in the absence of MARCO, macrophages are more susceptible to a greater inflammatory response by particulates known to cause NLRP3 inflammasome activation and the effect is due to increased LMP.

Description

Species	Human
Expression System	HEK293
Tag	N-His
Accession Number	Q9UEW3-1
Synonyms	Ly112, SCARA2, AI323439, MARCO
Construction	Recombinant Human MARCO Protein is expressed from HEK293 with His tag at the N-Terminus. It contains Ser405-Val520.[Accession \|Q9UEW3-1]
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	The protein has a predicted MW of 13.8 kDa. Due to glycosylation, the protein migrates to 14-20 kDa based on Tris-Bis PAGE result.

Endotoxin	Less than 1EU per μg by the LAL method.
Formulation	Lyophilized from 0.22μm filtered solution in PBS, 200mM L-arginine (pH 8.0). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability & Storage	-20 to -80°C for 12 months as supplied from date of receipt. -20 to -80°C for 3-6 months in unopened state after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Shipping	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.
