The RY ELISA kits listed below utilize specific antibodies for the plate-based assay of RY in various samples. RY is another term for the HSPA4 gene, which encodes the protein, heat shock protein family A (Hsp70) member 4 in humans. It has been reported that RY plays a role in protein folding, among other functions. Structurally, the HSPA4 protein is 840 amino acid residues in length and 94.3 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cytoplasm of the cell. Other names for this target antigen include APG-2, HEL-S-5a, and HS24/P52.
