ISG15 Antibody (703132RP647) in ICC/IF
Immunofluorescent analysis of ISG15 was performed using 70% confluent untreated and mouse IFN alpha (500 U/ml for 24 h) treated RAW 264.7 cells . The cells were fixed with 4% paraformaldehyde for 10 minutes, stained with Wheat Germ Agglutinin, Alexa Fluor™ 488 for 10 mins and permeabilized with 0.1% Triton X-100 for 15 minutes and blocked with 2% BSA for 1 hour at room temperature. The cells were stained with ISG15 Recombinant Rabbit Monoclonal Antibody (1H9L21), Alexa Fluor™ Plus 647 (Product # 703132RP647, 1:100) and Lamin B1 Recombinant... View More

Product Specific Information
Alexa Fluor™ Plus recombinant antibodies are conjugated using new, proprietary dye chemistry so you can generate stunning data. Alexa Fluor™ Plus antibodies represent an advancement in fluorescent conjugate technology. Alexa Fluor™ Plus antibodies provide brighter signal compared to leading Alexa Fluor™ antibodies, providing you with better signal-to-noise for your critical experiments. These antibodies show better specificity and lot-to-lot consistency as these are recombinant antibodies, generated by cloning specific genes for the desired antibodies into an expression vector and expressed in vitro.
Using conjugate solutions: Centrifuge the protein conjugate solution briefly in a microcentrifuge before use; add only the supernatant to the experiment. This step will help eliminate any protein aggregates that may have formed during storage, thereby reducing nonspecific background staining.
Applications Tested: This antibody has been tested by western blot, immunocytochemistry and flow cytometric analysis of 3T3-L1 and RAW 264.7 cells treated with mouse IFN alpha. This may be used for immunocytochemistry at 10 µg/ml and for flow cytometry at less than or equal to 0.25 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.

Target Information
Ubiquitin-like protein ISG15 plays a key role in the innate immune response to viral infection either via its conjugation to a target protein (ISGylation) or via its action as a free or unconjugated protein. It is secreted from monocytes in response to type I interferons and causes natural killer (NK)-cell proliferation and an augmentation of non-MCH (major histocompatibility complex)-restricted cytotoxicity. Synthesis is stimulated by IFN-alpha or IFN-beta or IFN-omega, but not IFN-gamma. ISG15 expression is also induced by overexpression of interferon regulatory factors that participate in transcriptional regulation of IFN genes, and by influenza B virus. ISG15 is secreted by cell lines of monocyte, T-lymphocyte, B-lymphocyte, human fibroblasts, and epithelial origins. Enhancement of NK cell proliferation, augmentation of non-major histocompatibility complex-restricted cytotoxicity, and induction of IFN-gamma from T cells identify ISG15 as a member of the cytokine cascade and suggest that it may be responsible for amplifying and directing some of the immunomodulatory effects of IFN-alpha or IFN-beta. ISG15 has has also been shown to function intracellularly as a ubiquitin homolog. Mutations affecting the gene can result in Immunodeficiency 38, with basal ganglia calcification (IMD38).
