Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
Purification The recombinant Fab was purified from tissue culture supernatant by affinity chromatography.
Alternative Name VASA/DDX4 (DDX4 Antibody Abstract)
Background The R11-A3 Fab reacts with a protein of the Asp-Glu-Ala-Asp (DEAD) box (DDX) family that is homologous to the VASA protein of Drosophila. The VASA/DDX4 gene is conserved in invertebrate and vertebrate species, and its expression is germ cell specific. In the human, VASA/DDX4 is expressed in fetal and adult germ cells, both male and female, but not in other fetal and adult tissues. Studies of VASA/DDX4 expression in various types of tumors suggest that expression of VASA/DDX4 is a useful biomarker for germ cell cancers.
