About HLA D
HLA-DMA belongs to the HLA class II alpha chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DMA) and a beta chain (DMB), both anchored in the membrane. It is located in intracellular vesicles. DM plays a central role in the peptide loading of MHC class II molecules by helping to release the CLIP molecule from the peptide binding site. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). The alpha chain is approximately 33-35 kDa and its gene contains 5 exons. Exon one encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, exon 4 encodes the transmembrane domain and the cytoplasmic tail. [provided by RefSeq, Jul 2008]

About PerCP
Peridinin-Chlorophyll-Protein (PerCP) is a red-emitting fluorescent protein isolated from algae that can be excited by the 488 nm blue laser and captured with a 670/30 nm bandpass filter. PerCP exhibits a large Stokes' Shift, with an excitation peak at 482 nm and an emission peak at 675 nm. PerCP is was historically used in flow cytometry, however it is highly susceptible to photobleaching and has poor stability. Alternatives like BB700, NovaFluor Blue 690 or PerCP-eFluor™ 710 are preferred. PerCP is a generic dye that has no sole manufacturer.
