kindly enlighten me regarding the the NRAMP! elisa kit, as per the sample types required, shown on this page it is can be assayed in serum or plasma. my question is that do we have it in our serum/plasma in routine?
i am currently working on Genetic susceptibility to tuberculosis in relation to SLC11A1 polymorphism
this gene produces the NRAMP1 protein on human macrophages
so i was intending to quantify this protein in serum / plasma of Tb patients and compare it with levels in serum of controls
so all i want to ask is CAN it be Quantified in Serum samples


Thanks for your kind patience!
#CSB-E17597h,this kit is designed and developed under the reference of is used to test NRAMP-1 protein.If you use TB serum and control serum as corresponding test group and control group,pls take actual meansurement as the real results.

Target Data

Function Divalent transition metal (iron and manganese) transporter involved in iron metabolism and host resistance to certain pathogens. Macrophage-specific membrane transport function. Controls natural resistance to infection with intracellular parasites. Pathogen resistance involves sequestration of Fe(2+) and Mn(2+), cofactors of both prokaryotic and eukaryotic catalases and superoxide dismutases, not only to protect the macrophage against its own generation of reactive oxygen species, but to deny the cations to the pathogen for synthesis of its protective enzymes.
