Sandwich ELISA quantitative detection kit for Human MyD88 in cell culture supernates.Myeloid differentiation primary response gene (88) (MYD88) is a protein that, in humans, is encoded by the MYD88 gene. By interspecific backcross mapping, the mouse MyD88 gene was localized to chromosome 9, the human homolog was mapped to 3p22-p21.3 The human ortholog MYD88 seems to function similarly to mice, however, available evidence suggests that MYD88 is dispensable for human resistance to common viral infections and to all but a few pyogenic bacterial infections, demonstrating a major difference between mouse and human immune responses.
