These NEGF2 ELISA kits are immunodetection tools for measuring the levels of NEGF2 in biological samples. NEGF2 is an alias of the human MDK gene, which encodes the protein, midkine. Notably, NEGF2 is known to play a role in cell differentiation and nervous system development, among other functions. The MDK protein is 143 amino acid residues in length and 15.6 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is known to be a secreted protein. In terms of tissue specificity, it is reported to be expressed in various tumor cell lines. Other names for this target antigen include ARAP and MK.
