Description

Rat Monoclonal Antibody

Description: The C17.8 antibody reacts with the p40 subunit of IL-12 and IL-23. The C17.8 antibody has been found to neutralize IL-12 and IL-23 bioactivity. For specific neutralization of IL-23 only, please see clone G23-8 (anti-mouse IL-23 p19). IL-12 is a 70 kDa heterodimeric cytokine composed of two covalently linked chains, p40 and p35, and is secreted by activated monocytes, macrophages, and dendritic cells. IL-23 is a heterodimer composed of the disulfide-linked p19 protein and p40 protein, expressed by activated dendritic cells. Applications Reported: This C17.8 antibody has been reported for use in intracellular staining followed by flow cytometric analysis. Applications Tested: This C17.8 antibody has been tested by intracellular staining and flow cytometric analysis of stimulated mouse cells. This can be used at less than or equal to 0.125 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. eFluor® 660 is a replacement for Alexa Fluor® 647. eFluor® 660 emits at 659 nm and is excited with the red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome. Excitation: 633-647 nm; Emission: 668 nm; Laser: Red Laser. Filtration: 0.2 μm post-man...

IL-12 is an interleukin produced by dendritic cells, neutrophils, macrophages and human lymphoblastoid cells as a result of antigenic stimulation. IL-12 is a heterodimeric cytokine encoded by IL-12A (p35) and IL-12B (p40). IL-23 is a heterodimeric cytokine that shares a subunit with IL-12 (IL-12B) along with an IL-23A (IL-23p19) subunit. Functionally, IL-12 increases the expression of vascular endothelial adhesion molecule-1 on the endothelium, directs leukocytes towards tumors and facilitates the ischemic-hemorrhagic necrosis of the tumor tissue. In comparison, IL-23 plays an important role in stimulating memory T-cells, and is required for the induction, expansion, maintenance and downstream effector functions of Th17 cells, which play a vital role in upregulating neutrophil chemokines and various pro-inflammatory cytokines.

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).

Is the eFluor 660 fluorochrome compatible with Anti-Cy5/Alexa Fluor 647 beads?

Yes, in-house studies have demonstrated that the eFluor 660 fluorochrome is recognized by Anti-Cy5/Alexa Fluor 647 beads. Side by side studies with Alexa Fluor 647 versus eFluor 660 conjugated antibodies have demonstrated comparable results.

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.
