The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/500 - 1/1000. Detects a band of approximately 11 kDa (predicted molecular weight: 17 kDa).
FunctionPerforms a specialized role during sperm development and maturation.
Tissue specificityProximal caput region of the epididymis. Lower expression in the testis. Within the testis it is localized to the elongating spermatids, whereas within the epididymis it is exclusively synthesized by the proximal caput epithelium.
Sequence similaritiesBelongs to the cystatin family.
