Beclin 1 Antibody Pack

Simple Western: Beclin 1 Antibody Pack [NB910-95609] - Lane view shows a specific band for Beclin in 1.0 mg/ml of HeLa lysate using NB110-87318. This experiment was performed under reducing conditions using the 12-230 kDa separation system.

Western Blot: Beclin 1 Antibody Pack [NB910-95609] - Expression of Beclin 1 mRNA and protein in cells and tissues. (A) Beclin 1 mRNA expression level up-regulated in gastric cancer cell lines compared with normal gastric epithelial cells by reverse transcription-PCR. (B) Beclin 1 protein expression level up-regulated in gastric cancer cell lines compared with normal gastric epithelial cells by western blotting. (C) Beclin 1 mRNA expression is elevated in primary gastric tumors compared with paired gastric adjacent noncancerous tissues by reverse transcription-PCR.

Immunohistochemistry: Beclin 1 Antibody Pack [NB910-95609] - Analysis of a FFPE tissue section of human breast cancer using Beclin 1 antibody (NB110-87318) at 1:300 dilution. The primary antibody bound to Beclin 1 antigen in the tissue section was detected using a HRP labeled secondary antibody and DAB reagent. Nuclei of the cells were counterstained with hematoxylin. Cytoplasmic staining can be seen in the cancer as well as the stromal cells. The signal was strongest in a subset of stromal cells which appears to be the cancer associated fibroblasts.

Knockdown Validated: Beclin 1 Antibody Pack [NB910-95609] - siRNA knockdown of becn1 (Beclin 1). Lysates from OKP7 cells treated with non-targeting siRNA (non-target) or an siRNA pool directed against Beclin 1 (becn1) were analyzed by Western blot for Beclin 1 production using NB500-249. GAPDH was used as a loading control. Image collected and cropped by CiteAb from the following publication (//doi.org/10.1371/journal.ppat.1003394) licensed under a CC-BY license.

Immunocytochemistry/Immunofluorescence: Beclin 1 Antibody Pack [NB910-95609] - Beclin 1 antibody (NB500-249) was tested in HeLa cells with Dylight 488 (green, left panel). Nuclei and alpha-tubulin were counterstained with DAPI (blue) and Dylight 550 (red), shown in the overlay (right panel)

Background

Beclin 1 is the first identified mammalian gene to mediate autophagy and also has tumor suppressor and antiviral function. Autophagy, a process of bulk protein degradation through an autophagosomic-lysosomal pathway, is important for differentiation, survival during nutrient deprivation, and normal growth control, and is often defective in tumor cells. Beclin 1 was originally isolated in a yeast two hybrid screen to identify Bcl-2-binding partners and maps to a tumor susceptibility locus on human chromosome 17q21 that is frequently monoallelically deleted in human breast, ovarian and prostate cancer. Beclin 1 encodes an evolutionarily conserved 60 kDa coiled coil protein that is expressed in human muscle, epithelial cells and neurons. In gene transfer studies, beclin 1 promotes nutrient deprivation-induced autophagy, inhibits mammary tumorigenesis, and inhibits viral replication. Expression of the Beclin 1 protein is frequently decreased in malignant breast epithelial cells. Based upon these observations, it is speculated that beclin 1 may work through induction of autophagy to negatively regulate tumorigenesis and to control viral infections. Beclin 1 may also play a role in other biological processes in which autophagy is important such as cell differentiation and nutritional stress responses.
