FLI1 Antibody / ETS Transcription Factor Marker [clone FLI1/4371R] (V4217)

FLI1 Antibody Ewing Sarcoma IHC. Immunohistochemistry analysis of FFPE human Ewing sarcoma tissue stained with FLI1 Antibody / ETS Transcription Factor Marker (clone FLI1/4371R). Strong nuclear HRP-DAB brown staining is observed within tumor cell populations, consistent with the expected nuclear localization of Friend leukemia integration 1 / FLI1, an ETS family transcription factor associated with EWSR1-FLI1-driven oncogenic transcriptional signaling pathways in Ewing sarcoma biology. Sections underwent HIER using 10mM Tris with 1mM EDTA buffer, pH 9, prior to immunostaining.

FLI1 Antibody EWS Tissue IHC. Immunohistochemistry analysis of FFPE human Ewing sarcoma (EWS) tissue stained with FLI1 Antibody / ETS Transcription Factor Marker (clone FLI1/4371R). Diffuse nuclear HRP-DAB brown staining highlights malignant tumor cells, supporting expression of Friend leukemia integration 1 / FLI1 within Ewing sarcoma-associated transcriptional regulatory pathways. Tissue sections underwent HIER using 10mM Tris with 1mM EDTA buffer, pH 9, followed by staining with recombinant rabbit monoclonal antibody clone FLI1/4371R.

FLI1 Antibody Daudi WB. Western blot analysis of human Daudi cell lysate using FLI1 Antibody / ETS Transcription Factor Marker (clone FLI1/4371R). A prominent band is detected near approximately 50 kDa, consistent with the predicted molecular weight of Friend leukemia integration 1 / FLI1, a nuclear ETS family transcription factor involved in hematopoietic differentiation and oncogenic transcriptional regulation pathways.

FLI1 Antibody HuProt Microarray Specificity Validation. Analysis of a HuProt(TM) microarray containing more than 19,000 full-length human proteins using FLI1 Antibody / ETS Transcription Factor Marker clone FLI1/4371R demonstrates highly selective recognition of Friend leukemia integration 1 / FLI1. The intended FLI1 target ranks first among all proteins analyzed on the array, with exceptionally strong separation from secondary signals, supporting the specificity profile of this recombinant rabbit monoclonal antibody for ETS family transcription factor and oncology research applications. Z-score represents signal intensity above background in standard deviation units, while S-score reflects the relative specificity of antibody binding compared with additional proteins present on the HuProt(TM) platform.
