Description: SMADs are members of the MAD-related family of molecules. MAD-related proteins are a family of intracellular proteins that are essential components in the signaling pathways of the serine/threonine kinase receptors of the transforming growth factor beta superfamily. Alterations in the SMAD4 gene was primarily discovered in pancreatic cancer (duct adenocarcinoma) but occur in a variety of cancers such as colorectal cancer, gastric cancer, prostate cancer, melanomas, head and neck cancers and many others, though with higher frequencies in gastrointestinal tract cancers. Loss of SMAD4 expression in tumors has also been shown to affect cancer progression and therapy, such as reduced response to adjuvant chemotherapy.

Supplier: Diagnostic Biosystems
Description: This antibody reacts with wild as well as mutant types of P53 protein. It recognizes an epitope in the N-terminus of P53 protein, known to reside between amino acids 35 to 45. This antibody can be demonstrated in 22 to 76% of the colon, stomach, bladder, breast, lung and testes cancers.

Supplier: Diagnostic Biosystems
Description: This antibody reacts specifically with CA 125 ovarian cancer antigen. Several studies have shown that CA 125 is a useful tumor marker for ovarian epithelial malignancies. However, CA 125 has been described in other neoplasms such as seminal vesicle and anaplastic lymphomas.

Catalog Number: (CA76634-490)
Supplier: Diagnostic Biosystems
Description: It recognizes a protein of 15kDa, identified as Gross cystic disease fluid protein 15 (GCDFP-15). It is a major protein component of benign breast gross cysts. It is a known marker of breast cancer, as it is found in approximately 50% of all breast cancer specimens. GCDFP-15, also known as PIP, for prolactin inducible protein, is a prolactin and androgen controlled protein. This antibody is useful in the identification of metastatic breast carcinoma, or fluid analysis.

Description: The programmed death receptor 1 (PD-1) protein is a cell-surface receptor on certain lymphocytes that, with its ligand programmed death ligand 1 (PD-L1), helps to down-regulate immune responses. Many cancer types express PD-L1 and evade immune recognition via the PD-1/PD-L1 interaction. Precision therapies targeting the PD-1/PD-L1 pathway have the potential to improve response and thereby offer a novel treatment avenue to some patients with cancer.

Supplier: Diagnostic Biosystems
Description: Galectin-3 is a member of the beta-galactoside-binding protein family that plays an important role in cell adhesion, cell matrix interactions, macrophage activation, angiogenesis, metastasis, and apoptosis.

Galectin-3 shows strong diffuse cytoplasmic staining in most cases of papillary thyroid carcinoma (PTC), most poorly differentiated thyroid cancers demonstrate galectin-3 protein expression while it is not expressed in anaplastic thyroid cancers. (1) Upregulated expression of galectin-3 is involved in cancer progression and metastasis, and it is suggested that Galectin-3 may be a valuable tool to support diagnosis of parathyroid carcinoma. (2)

Galectin-3 has also been reported to play important roles in the progression of prostate cancer, and their heterogeneous expressions might be associated with different cancer subtypes. (3)


Catalog Number: (CA76634-350)
Supplier: Diagnostic Biosystems
Description: This antibody is specific to an oncofetal antigen of >1000 kDa known as tumor associated glycoprotein (TAG-72) or CA 72-4. This antibody defines the mucin carried sialylated-Tn antigen. This antibody stains the majority of human adenocarcinomas including colorectal, pancreatic, gastric, ovarian, endometrial, mammary and non-small cell lung cancer.

Supplier: Diagnostic Biosystems
Description: Postmeiotic segregation increased 2 or PMS2 was originally discovered in S. cerevisiae and is part of the mismatch repair system. It resides on 7p22.2 and its gene product partner with MLH1 to help detect mismatches in DNA. Mutations in PMS2 have been reported in about two percent of families with Lynch syndrome (hereditary nonpolyposis colorectal cancer).


Supplier: Diagnostic Biosystems
Description: This antibody recognizes a c-erbB-2 protein, which is a receptor tyrosine kinase of the c-erbB family. It is closely related in structure to the epidermal growth factor receptor. c-erbB-2 oncoprotein is detectable in a subset of breast and other adenocarcinomas, as well as transitional cell carcinomas. In the case of breast cancer, expression determined by immunohistochemistry has been shown to be associated with poor prognosis.
