These 4.1G ELISA kits are immunodetection tools for measuring the levels of 4.1G in biological samples. 4.1G is an alias name of the human EPB41L2 gene, which encodes the protein, erythrocyte membrane protein band 4.1 like 2. Notably, 4.1G is known to play a role in the cell cycle, among other functions. The EPB41L2 protein is 1005 amino acid residues in length and 112.6 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. It is localized to the cell membrane and cytoplasm of the cell. In terms of tissue specificity, it is widely expressed across many tissue types. Other names for this target antigen include 4.1-G.
