Product Image Gallery

IL-13 Antibody — Fig. 6 IRE1a-XBP1 pathway is required for cytokine expression and secretion in Th2 lymphocyte. Naive T helper cells were cultured following Th2 activation condition in the presence of IRE1a inhibitor 4mu8c for 3 days, rested for 2 days, reactivated by coated plate, and analyzed by flow cytometry to detect intra-cellular cytokines IL4, IL5, and IL13 expression. Representative FACS profiles are displayed in the first two columns. The intra-cellular cytokine expression is compared in column 3, with three to seven independent biological replicates. Fourth column: cell culture supernatants from 4mu8c-treated or DMSO-treated Th2 were analyzed by ELISA to measure the cytokine concentration. FACS gating: lymphocytes > singlets > live cells > cytokines

IL-13 Antibody in Flow Cytometry (Flow) — CD4+ BALB/c splenocytes were stimulated for 10-days under Th2 polarizing conditions. Cells were then restimulated with Cell Stimulation Cocktail (plus protein transport inhibitors) (Product # 00-4975-03) for 5 hours. Following restimulation, cells were fixed and permeabilized using the Intracellular Fixation and Permeabilization Buffer Set (Product # 88-8824-00) and then stained with Anti-Mouse CD4 eFluor® 450 (Product # 48-0042-82) and 0.25 µg of Rat IgG1 K Isotype Control PE-Cyanine7 (Product # 25-4301-82) (left) or 0.25 µg of Anti-Mouse IL-13 PE-Cyanine7 (right). Viable cells, as determined by Fixable Viability Dye eFluor® 660 (Product # 65-0864-14), were used for analysis.

Product Specific Information

Description: The eBio13A antibody reacts with mouse IL-13. IL-13 is a cytokine produced mainly by Th2 cells, but also by antigen-primed CD8 T cells. IL-13 has a strong involvement in allergic inflammation and parasitic clearing and in cancer models has been shown to have either inhibitory or stimulatory activity depending on the tumor. In humans, IL-13 is found to play a role in isotype switching in B cells. IL-13 is implicating in down modulating macrophage activity, through the reduction of pro-inflammatory cytokines (IL-1, IL-6, IL-8, IL-10, IL-12)

Applications Reported: This eBio13A antibody has been reported for use in intracellular staining followed by flow cytometric analysis.

Applications Tested: This eBio13A antibody has been tested by intracellular staining of stimulated mouse splenocytes. This can be used at less than or equal to 0.5 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.

Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light.

Fixation: Samples can be stored in IC Fixation Buffer (cat. 00-8222) (100 µL cell sample + 100 µL IC Fixation Buffer) or 1-step Fix/Lyse Solution (cat. 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.

Excitation: 488-561 nm; Emission: 775 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser.

Filtration: 0.2 µm post-manufacturing filtered.

Target Information

IL-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells, and is involved in regulating inflammatory and immune responses. IL-13 down-regulates macrophage activity, thereby inhibiting the production of pro-inflammatory cytokines and chemokines, and is involved in allergen-induced asthma through mechanisms independent of IgE and eosinophils. IL-13 also regulates several stages of B cell maturation and differentiation, up-regulates CD23 and MHC class II expression, and promotes IgE isotype switching of B cells. Structurally, IL-13 closely resembles IL-3, IL-4, IL-5 and GM-CSF. The gene encoding IL-13, IL3, IL5, IL4, and CSF2 form a cytokine gene cluster on chromosome 5q, with the IL-13 gene particularly close to IL4.
