This assay has high sensitivity and excellent specificity for detection of Deleted In Malignant Brain Tumors 1 (DMBT1). No significant cross-reactivity or interference between Deleted In Malignant Brain Tumors 1 (DMBT1) and analogues was observed.

For unopened kit: All the reagents should be kept according to the labels on vials. The Standard, Detection Reagent A, Detection Reagent B and the 96-well strip plate should be stored at -20 degree C upon receipt while the others should be at 4 degree C. For opened kit: When the kit is opened, the remaining reagents still need to be stored according to the above storage condition. Besides, please return the unused wells to the foil pouch containing the desiccant pack, and reseal along entire edge of zip-seal. The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Samples: Tissue homogenates, lung lavage fluid and other biological fluids. Assay Type: Sandwich. Detection Range: 0.156-10ng/mL. Sensitivity: Typically less than 0.056ng/mL.

Precision: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Deleted In Malignant Brain Tumors 1 (DMBT1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Deleted In Malignant Brain Tumors 1 (DMBT1) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 . Intra-Assay: CV<10% . Inter-Assay: CV<12% . Assay Procedure Summary: 1. Prepare all reagents, samples and standards;. 2. Add 100uL standard or sample to each well. Incubate 2 hours at 37 degree C;. 3. Aspirate and add 100uL prepared Detection Reagent A. Incubate 1 hour at 37 degree C;. 4. Aspirate and wash 3 times;. 5. Add 100uL prepared Detection Reagent B. Incubate 30 minutes at 37 degree C;. 6. Aspirate and wash 5 times;. 7. Add 90uL Substrate Solution. Incubate 15-25 minutes at 37 degree C;. 8. Add 50uL Stop Solution. Read at 450nm immediately.

Principle of the Assay: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Deleted In Malignant Brain Tumors 1 (DMBT1). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Deleted In Malignant Brain Tumors 1 (DMBT1). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Deleted In Malignant Brain Tumors 1 (DMBT1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm 10nm. The concentration of Deleted In Malignant Brain Tumors 1 (DMBT1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Salivary Secretion Pathway (153376); Salivary Secretion Pathway (153352)

Loss of sequences from human chromosome 10q has been associated with the progression of human cancers. The gene DMBT1 was originally isolated based on its deletion in a medulloblastoma cell line. DMBT1 is expressed with transcripts of 6.0, 7.5, and 8.0 kb in fetal lung and with one transcript of 8.0 kb in adult lung, although the 7.5 kb transcript has not been characterized. The DMBT1 protein is a glycoprotein containing multiple scavenger receptor cysteine-rich (SRCR) domains separated by SRCR-interspersed domains (SID). Transcript variant 2 (8.0 kb) has been shown to bind surfactant protein D independently of carbohydrate recognition. This indicates that DMBT1 may not be a classical tumor suppressor gene, but rather play a role in the interaction of tumor cells and the immune system. [provided by RefSeq, Nov 2014]

DMBT1: May be considered as a candidate tumor suppressor gene for brain, lung, esophageal, gastric, and colorectal cancers. May play roles in mucosal defense system, cellular immune defense and epithelial differentiation. May play a role as an opsonin receptor for SFTPD and SPAR in macrophage tissues throughout the body, including epithelial cells lining the gastrointestinal tract. May play a role in liver regeneration. May be an important factor in fate decision and differentiation of transit-amplifying ductular (oval) cells within the hepatic lineage. Required for terminal differentiation of columnar epithelial cells during early embryogenesis. May function as a binding protein in saliva for the regulation of taste sensation. Binds to HIV-1 envelope protein and has been shown to both inhibit and facilitate viral transmission. Displays a broad calcium-dependent binding spectrum against both Gram-positive and Gram-negative bacteria, suggesting a role in defense against bacterial pathogens. Binds to a range of poly- sulfated and poly-phosphorylated ligands which may explain its broad bacterial-binding specificity. Inhibits cytoinvasion of S.enterica. Associates with the actin cytoskeleton and is involved in its remodeling during regulated exocytosis. Interacts with pancreatic zymogens in a pH-dependent manner and may act as a Golgi cargo receptor in the regulated secretory pathway of the pancreatic acinar cell. Defects in DMBT1 are involved in the development of glioma (GLM). Gliomas are central nervous system neoplasms derived from glial cells and comprise astrocytomas, glioblastoma multiforme, oligodendrogliomas, and ependymomas. Homozygous deletions may be the predominant mechanism of DMBT1 inactivation playing a role in carcinogenesis. DMBT1 is deleted in medulloblastoma and glioblastoma cell lines; point mutations have also been reported in patients with glioma. A loss or reduction of DMBT1 expression has been seen in esophageal, gastric, lung and colorectal carcinomas as well. Belongs to the DMBT1 family. 8 isoforms of the human protein are produced by alternative splicing. Protein type: Membrane protein, integral; Oncoprotein; Secreted, signal peptide; Tumor suppressor; Secreted. Chromosomal Location of Human Ortholog: 10q26.13. Cellular Component: proteinaceous extracellular matrix; extracellular space; phagocytic vesicle membrane; zymogen granule membrane; extrinsic to membrane; cytoplasm; extracellular region. Molecular Function: protein binding; calcium-dependent protein binding; scavenger receptor activity; pattern recognition receptor activity. Biological Process: induction of bacterial agglutination; receptor-mediated endocytosis; protein transport; epithelial cell differentiation; viral reproduction; innate immune response; positive regulation of epithelial cell differentiation; pattern recognition receptor signaling pathway; defense response to virus; inner cell mass cell proliferation.
