The TNFRSF9 Antibody, HRP Conjugated, is a primary antibody against the extracellular domain of TNFRSF9, covalently linked to horseradish peroxidase (HRP). This conjugation enables enzymatic detection of TNFRSF9 without requiring secondary antibodies, streamlining workflows for high-throughput assays.
The HRP-conjugated TNFRSF9 antibody is validated for diverse immunodetection methods:
a. ELISA
Used in sandwich or direct ELISA to quantify TNFRSF9 expression in cell lysates or serum. Example: Cusabio’s CSB-PA08109B0Rb (HRP-conjugated) detects TNFRSF9 in ELISA with high specificity .
b. Western Blot
Detects TNFRSF9 in denatured protein samples. R&D Systems’ unconjugated AF838 antibody (cited in sources) shows bands at 50–65 kDa in HEK293T lysates, while HRP-conjugated variants eliminate secondary antibody steps .
c. Immunohistochemistry (IHC)
Localizes TNFRSF9 in tissue sections (e.g., human tonsil lymphocytes) using chromogenic or fluorescent detection .
d. Flow Cytometry
Though primarily unconjugated antibodies are used (e.g., AF838 in PHA-treated T cells), HRP conjugates may enable enzymatic-based detection in specialized protocols .
TNFRSF9 antibodies are pivotal in studying immune modulation and cancer immunotherapy:
