Species Reactivity
Intended Use
This Human Soluble LDLR ELISA Kit contains the necessary components required for the quantitative measurement of recombinant and/or natural human LDLR from serum and plasma in a sandwich ELISA format.
This immunoassay contains recombinant human LDLR and antibodies raised against this protein. Results from this immunoassay have shown to accurately quantify recombinant and natural LDLR samples.
Contents of Kit
