Description

Mouse Monoclonal Antibody

Description: This ebic6 monoclonal antibody reacts with human Epstein-Barr Virus Induced Gene 3 (EBI3). EBI3 can be expressed and secreted as monomers or homodimers, and was first identified in virally-infected B cells. It is also believed to be secreted as a homodimer by cells of the trophoblast, where it may play a role in immune tolerance during pregnancy. Additionally, EBI3 is a component of two of the four members of the interleukin (IL)-12 family of heterodimeric cytokines. EBI3 was first found to heterodimerize with p28 (IL-30) to form IL-27, which is secreted by antigen-presenting cells in response to pro-inflammatory stimuli. IL-27 has been shown to have both pro-inflammatory and anti-inflammatory effects. It influences the commitment of CD4+ T-cells toward the Th1 lineage by inducing the expression of the T-bet transcription factor and the upregulation of IL-12R beta 2. Its anti-inflammatory functions include the suppression of Th2 and Th17 proliferation and differentiation. More recently, EBI3 was also found to dimerize with the IL-12 subunit, p35 to form IL-35. The biology of IL-35 is incompletely understood, but it is believed to be unique among the IL-12 family members in its expression and function. It is produced by regulatory T cells, and appears to have immunoregulatory functions. IL-35 has been found to suppress the proliferation and function of effector T cells, and has also been observed to induce a regulatory phenotype on naive CD4+ cells cultured in...

EBI3 (Epstein-Barr virus Induced-3) is a secreted glycoprotein of the hematopoietin receptor family. It plays a critical regulatory role in the induction of Th2-type immune responses and the development of Th2-mediated tissue inflammation in vivo, which may be mediated through the control of iNKT cell function. EBI3 dimerizes with p28 and p35 subunits of IL-12 to form new proteins IL-27 and IL-35, respectively. IL-27 is an early product of activated antigen presenting cell that is produced upon TLR ligation. It negatively regulates Th17 cell differentiation. EBI3 is widely expressed and its expression in dendritic cell is transcriptionally regulated by TLR signaling via MyD88 and NF-kappaB during innate immune responses preceding cytokine driven Th cell development. EBI3 signal inhibits delayed-type hypersensitivity responses by suppressing IL-17 production and inducing IL-10 hyperproduction. EBI3 may play a novel role in controlling tumor metastasis via lung CD8+ T cells, and its deficiency is associated with a diminished production of Th2 cytokines which are known to regulate allergic airway inflammation in asthma. Targeted deletion of EBI3 protects mice from lung metastasis.

Frequently Asked Questions (FAQs)

I am unable to analyze my cells stained with eFluor Organic Dyes today. What options do I have?

Our options will depend on the samples you are analyzing.

If cell viability is not critical, you can store your stained samples at 4 degrees C or on ice overnight in the dark and analyze the following day.

For samples stained with eFluor organic fluorochromes, we recommend that cells be suspended in 100 uL of Flow Cytometry Staining Buffer (Cat. No. 00-4222) and 100 uL of eBioscience IC Fixation Buffer (Cat. No. 00-8222); samples can be incubated for up to 3 days at 4 degrees C in the dark. Alternatively, the 1-step Fix/Lyse Solution (Cat. No. 00-5333) can be used. This is a great option when working with whole blood but also works for other cell types.

Can the eFluor Organic fluorochromes be used for intracellular staining?

Yes, the eFluor Organic fluorochromes can be used for intracellular staining. The eFluor organic fluorochromes maintain bright signal and require minimal changes in compensation when fixed with eBioscience IC Fixation Buffer (Cat. No. 00-8222-49) and Permeabilization Buffer (Cat. No. 00-8333-56) or 1-step Fix/Lyse Solution (Cat. No. 00-5333-54, 00-5333-57) (as compared to live cells).

What buffers are compatible with the eFluor Organic fluorochromes and eVolve QDots?

The eFluor Organic fluorochromes and eVolve QDots can be used with flow staining buffers containing PBS and protein.

What is the difference between eFluor Organic Dyes and eVolve Qdots?

The eFluor Organic Dyes (eFluor 450, APC-eFluor 780, PerCP-eFluor 710, eFluor 710) are conventional fluorochromes. In contrast, the eVolve line of products are Quantum dots.

Are the eFluor Organic Dyes photo-labile?

As with other fluorochromes, we recommend minimal exposure to light to maintain optimal signal.
