CD28 / DyLight 550 / C28/77

Product Details

Description	Recognizes a glycoprotein of 44-88kDa, which is identified as CD28. It is the critical T-cell co-stimulatory receptor which provides to the cell the important second activation signal by binding CD80 and CD86 that are expressed by antigen presenting cells. Besides its co-stimulation role, CD28 functions in preventing T-cells from anergic hyporesponsive state or from undergoing premature apoptotic cell death. CD28 is also expressed on human fetal NK cells and some NK cell lines, whereas on murine NK cells the CD28 expression is much broader.

About CD28
The protein encoded by this gene is essential for T-cell proliferation and survival, cytokine production, and T-helper type-2 development. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2011]

About DyLight 550
DyLight™ 550 has an excitation peak at 562 nm and an emission peak at 576 nm and is spectrally similar to Alexa Fluor™ 546, Alexa Fluor™ 555, Cy3 and TRITC. DyLight™ 550 is most commonly used in flow cytometery and fluorescence microscopy applications.
