CUT&RUN was performed with HT-1080 cells treated with (hIFN-γ) #8901 (50 ng/ml, 30 min) and Stat1 (D1K9Y) Rabbit mAb or Rabbit (DA1E) mAb IgG XP® Isotype Control (CUT&RUN) #66362, using CUT&RUN Assay Kit #86652. The enriched DNA was quantified by real-time PCR using human AIM2 promoter primers, human FZD5 promoter primers, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
Simple Western™ analysis of lysates (0.1 mg/mL) from MCF-7 cells using Stat1 (D1K9Y) Rabbit mAb #14994. The virtual lane view (left) shows the target band (as indicated) at 1:10 and 1:50 dilutions of primary antibody. The corresponding electropherogram view (right) plots chemiluminescence by molecular weight along the capillary at 1:10 (blue line) and 1:50 (green line) dilutions of primary antibody. This experiment was performed under reducing conditions on the Jess™ ​​​​​​​ Simple Western instrument from ProteinSimple, a BioTechne brand, using the 12-230 kDa separation module.

Product Description

The IFN (Type I/III) Signaling Pathway Antibody Sampler Kit provides an economical means of detecting the activation of the IFN (Type I/III) signaling pathway using phospho-specific and control antibodies. The kit includes enough antibodies to perform two western blot experiments with each primary antibody.

Specificity / Sensitivity

Each antibody in the IFN (Type I/III) Signaling Pathway Antibody Sampler kit detects endogenous levels of its target protein. Phospho-Jak1 (Tyr1034/1035) (D7N4Z) Rabbit mAb can detect Jak1 when dually or singly phosphorylated at Tyr1034. This site has historically been referenced as Tyr1022 and Ty1023. Phospho-Tyk2 (Tyr1054/1055) (D7T8A) Rabbit mAb detects Tyk2 when phosphorylated at both Tyr1054 and Tyr1055. Cross-reactivity was not observed with other family members. Phospho-Stat1 (Tyr701) (D4A7) Rabbit mAb recognizes endogenous levels of Stat1 protein only when phosphorylated at Tyr701. Phospho-Stat2 (Tyr690) (D3P2P) Rabbit mAb recognizes endogenous levels of Stat2 protein only when phosphorylated at Tyr690. IRF-9 (D2T8M) Rabbit mAb cross-reacts with an unidentified protein of 95 kDa. Stat1 (D1K9Y) Rabbit mAb cross-reacts with an unidentified protein of 150 kDa. A band of unknown identity at 55 kDa is detected in some cell lines by Tyk2 (D4I5T) Rabbit mAb.

Source / Purification

Monoclonal antibodies are produced by immunizing rabbits with synthetic peptides corresponding to residues surrounding Ile800 of Jak1, Pro688 of Stat1, Leu706 of Stat2, the carboxy terminus of Tyk2, and with recombinant protein specific to IRF-9. Phosphorylation-specific monoclonal antibodies are produced by immunizing rabbits with synthetic peptides corresponding to residues surrounding Tyr1034/1035 of Jak1, Tyr1054/1055 of Tyk2, Tyr701 of Stat1, and Tyr690 of Stat2.

Background

Originally discovered in the late 1950s for their antiviral activity, interferons (IFNs) have since been assigned diverse roles in many physiological and pathological processes. There are three families of IFNs: types I, II, and III. In humans, type I contains IFN-α (13 different subtypes), IFN-β (also known as IFN-β1), IFN-ε, IFN-κ, and IFN-ω. They bind to a receptor complex containing IFNAR1 and IFNAR2, which is broadly expressed on most cells. IFN-γ is the sole member of type II IFN. It signals through a receptor complex consisting of IFNγR1 and IFNγR2, which is also expressed on most cell types. Type III IFN, also known as interferon lambdas (IFN-λs), have four members in humans: IFN-λ1 (IL29), IFN-λ2 (IL28A), IFN-λ3 (IL28B), and IFN-λ4. IFN-λs signal through a heterodimeric receptor comprised of IFNλR1 and IL-10R2. While IL-10R2 is broadly expressed and shared by the IL-10 family cytokines, IFNλR1 expression is restricted to epithelial cells, neuronal cells, and subsets of myeloid cells (1-3). Engagement of all IFNs with their receptors initiates downstream signaling events, mainly, activation of the Jak–Stat signaling cascade. For type I and III IFNs, Jak1 and Tyk2 are phosphorylated and activated, leading to subsequent phosphorylation of Stat1 and Stat2. Phosphorylated Stat1 and Stat2 are released from the receptor complex and, together with IRF-9, they form so-called ISGF3 (interferon-stimulated gene factor 3) transcriptional complex. ISGF3 translocates to the nucleus, binds to the interferon-stimulated response element (ISRE) to initiate the transcription of a wide array of interferon-stimulated genes (ISGs) (4,5). On the other hand, IFN-γ induces phosphorylation and activation of Jak1 and Jak2, which subsequently phosphorylate Stat1. Phosphorylated Stat1 dimerizes, translocates to the nucleus, and binds to γ-interferon-activated site (GAS) to initiate the transcription of ISGs (6,7).
