Recombinant full-length human protein was used as the immunogen for the CD43 antibody.
Conjugation:
Unconjugated
It recognizes a cell surface glycoprotein of 95/115/135kDa (depending upon the extent of glycosylation), identified as CD43. 70-90% of T-cell lymphomas and from 22-37% of B-cell lymphomas express CD43. No reactivity has been observed with reactive B-cells. So a B-lineage population that co-expresses CD43 is highly likely to be a malignant lymphoma, especially a low-grade lymphoma, rather than a reactive B-cell population. When CD43 antibody is used in combination with anti-CD20, effective immunophenotyping of the lymphomas in formalin-fixed tissues can be obtained. Co-staining of a lymphoid infiltrate with anti-CD20 and anti-CD43 argues against a reactive process and favors a diagnosis of lymphoma.
0.2 mg/ml in 1X PBS with 0.1 mg/ml rAlbumin and 0.05% sodium azide
Application Dilute:
Flow cytometry: 1-2ug/10 6 cells,Immunofluorescence: 1-2ug/ml,Western blot: 1-2ug/ml,Immunohistochemistry (FFPE): 1-2ug/ml for 30 min at RT
Application Notes:
Application Notes: Optimal dilution of the CD43 antibody should be determined by the researcher.1. Staining of formalin-fixed tissues requires boiling tissue sections in pH 9 10mM Tris with 1mM EDTA for 10-20 min followed by cooling at RT for 20 min.2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min
IHC: Formalin-fixed, paraffin-embedded human spleen stained with CD43 antibody (SPN/839).
Western blot analysis of human spleen lysate using CD43 antibody (SPN/839). Expected molecular weight: 45-115 kDa depending on glycosylation level.
Western blot analysis of human K562 lysate using CD43 antibody (clone SPN/839). Expected molecular weight: 45-135 kDa depending on glycosylation level.
Immunofluorescent staining of human K562 cells with CD43 antibody (clone SPN/839, green) and NucSpot nuclear stain (red).
Flow cytometry testing of human K562 cells with CD43 antibody (clone SPN/839), Red = isotype control, Blue = CD43 antibody.
SDS-PAGE analysis of purified, BSA-free CD43 antibody (clone SPN/839) as confirmation of integrity and purity.
