Mcl‑1 in Human Lymphoma. Mcl-1 was detected in immersion fixed paraffin-embedded sections of human lymphoma using Mouse Anti-Human Mcl-1 Monoclonal Antibody (Catalog # MAB8281) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counter-stained with hematoxylin (blue). Specific staining was localized to the cytoplasm and plasma membranes of lymphocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Mcl-1

Mcl-1 (myeloid cell leukemia-1) is a member of the Bcl-2 family of proteins. Alternative splicing creates two distinct isoforms. The 40 kDa, 350 amino acid (aa) isoform 1, also known as Mcl-1L (long), enhances cell survival by inhibiting apoptosis, while the ~35 kDa, 271 aa isoform 2, also known as Mcl-1S (short; with divergence in the last 41 aa) promotes apoptosis. The elimination of Mcl-1L is a required step for DNA damage-induced apoptosis. Mcl-1 can be modified by phosphorylation on S121 and T163 by JNK, which triggers apoptosis, or polyubiquitination, which enhances degradation. Within aa 231-350 (unique to Mcl-1L), human Mcl-1 shares 93% and 96% aa identity with mouse and rat Mcl-1, respectively.
