آنتی بادیهای ایمونوهیستوشیمیآنتی بادی CD20 کلون L26 برند Patho Sage
Specification:
This antibody reacts with a formalin-resistant intracytoplasmic epitope found in the majority of B cells and now considered to be the CD20 antigen, a pan-B cell marker. The antibody primarily recognizes a 33 kD polypeptide B cell component and also a minor 30 kD cellular antigen. The staining pattern is consistent with pan-B reactivity, producing staining for B cells in lymphoid and peripheral blood tissue. This antibody intensely stains germinal centers and B immunoblots in lymphoid tissue. The L26 antibody is widely regarded as the most selective B cell marker currently available. L26 has shown no cross reactivity with nonlymphoid tissues and there are several studies demonstrating its sensitivity and specificity in formalin fixed, paraffin-embedded tissues. Studies have demonstrated that, in cases of lymphocyte predominant Hodgkin’s lymphomas, L&H variants of Reed-Sternberg cells show a strong L26 reactive pattern that is distinctive from other Reed Sternberg variants. L26 may prove to be a useful marker for this particular subset of Hodgkin’s lymphomas.

آنتی بادی BAP1 کلون C-4 برند Patho Sage
Specification:
Mutations within the BRCA1 gene, localized to chromosome 17q, are believed to account for approximately 45% of families with increased incidence of both early-onset breast cancer and ovarian cancer. The BRCA1 gene is expressed in numerous tissues, including breast and ovary, and encodes a predicted protein of 1,863 amino acids. This protein contains a RING domain near the N-terminus and appears to encode a tumor suppressor. BARD1 (BRCA1-associated RING domain protein 1) and BAP1 (BRCA1-associated protein 1) have both been shown to bind to the N-terminus of BRCA1 and are potential mediators of tumor suppression. BARD1 contains an N-terminal RING domain and three tandem ankyrin repeats. The C terminus of BARD1 contains a region with sequence homology to BRCA1, termed the BRCT domain. BAP1 is a ubiquitin hydrolase and has been shown to enhance BRCA1-mediated cell growth suppression.

آنتی بادیهای ایمونوهیستوشیمیآنتی بادی YAP کلون 63.7 برند Patho Sage
Specification:
The Yes-associated protein, otherwise known as YAP, is a 14-3-3 binding molecule that was originally recognized by virtue of its ability to bind to the SH3 domain of Yes. The binding of YAP to 14-3-3 requires the phosphorylation of a homologous serine residue (Ser 112) in the YAP 14-3-3 binding motif. The highly conserved and ubiquitously expressed 14-3-3 proteins regulate differentiation, cell cycle progression and apoptosis by binding intracellular phosphoproteins involved in signal transduction. YAP may link events at the plasma membrane and cytoskeleton to inhibition of transcription in the nucleus in a manner regulated by 14-3-3 proteins. YAP shares homology with the WW domain of TAZ, transcriptional co-activator with PDZ binding motif, which functions as a transcriptional co-activator by binding to the PPXY motif present in transcription factors. YAP is expressed at high levels in the lung, placenta, prostate, ovary and testis.

آنتی بادیهای ایمونوهیستوشیمیآنتی بادی Kappa Immunoglobulin Light Chain کلون L1C1 برند Patho Sage
Specification:
This antibody is specific to kappa light chain of immunoglobulin and shows no cross-reaction with lambda light chain or any of the five heavy chains. In mammals, the two light chains in an antibody are always identical, with only one type of light chain, kappa or lambda. The ratio of Kappa to Lambda is 70:30. However, with the occurrence of multiple myeloma or other B-cell malignancies this ratio is disturbed. Antibody to the kappa light chain is reportedly useful in the identification of leukemias, plasmacytomas, and certain non-Hodgkin’s lymphomas. Demonstration of clonality in lymphoid infiltrates indicates that the infiltrate is malignant.
