Description

Description: The L243 mAb reacts with the human major histocompatibility complex (MHC) class II, HLA-DR. HLA-DR is expressed on the surface of human antigen presenting cells (APC) including B cells, monocytes, macrophages, DCs, and activated T cells. HLA-DR is a heterodimeric transmembrane protein composed of alpha and beta subunits and plays an important role in the presentation of peptides to CD4^+ T lymphocytes. The L243 antibody recognizes a different epitope than the LN3 monoclonal antibody, and these antibodies do not cross-block binding to each other's respective epitopes.

Experimental details

Western blot analysis of TRF2 in total protein from mouse 3T3 cells. Samples were incubated in TRF2 monoclonal antibody (Product # MA1-41001) using a dilution of 2.0 µg/mL followed by an anti-mouse HRP secondary antibody. Separated on a 12% gel by SDS-PAGE, transferred to PVDF membrane and blocked in 5% non-fat milk in TBST. Detection: chemiluminescence.

Experimental details

Western blot was performed using Anti-TRF2 Monoclonal Antibody (4A794.15) (Product # MA1-41001) and a 75 kDa band corresponding to TRF2 was observed across all cell lines tested. Modified whole cell extracts (1% SDS) (30 µg lysate) of THP-1 (Lane 1), SW-480 (Lane 2), MCF-10A (Lane 3) and MCF-7 (Lane 4)were electrophoresed using NuPAGE® 4-12 % Bis-Tris gel (Product # NP0321BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (2ug/ml) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L), Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

Immunohistochemical analysis of TRF2 in Transitional cell carcinoma, urinary bladder. Samples were incubated in TRF2 monoclonal antibody (Product # MA1-41001) using a dilution of 4 µg/mL followed by a peroxidase-conjugate and DAB chromogen. Note specific nuclear staining. Tumor/normal adjacent tissue array slide was used for this test. Staining of formalin-fixed tissues is enhanced by boiling tissue sections in 10 mM sodium citrate buffer, pH 6.0 for 10-20 min followed by cooling at RT for 20 min.

Figure 3 Toxic concentrations of antidepressants promote DNA fragmentation of treated cells. GC-1 spg and GC-2 spd cells were treated with antidepressants for 48 and 96 h. The TUNEL labeling system to detect the DNA damage was then applied ( A , C ) and the level of TRF1, TRF2 proteins were controlled by Western blot technique. Representative blots ( B , D ) and photos of TUNEL cells are shown (magnification 10x). Blue fluorescence (DAPI) live cells, green fluorescence (FITC) apoptotic cells. Statistical differences were determined using one-way analysis of variance (ANOVA) with Dunnett's post-hoc test; p values < 0.05 were considered statistically significant. Asterisks (*) indicate the comparison between control and antidepressants-treated cells, whereas carets (^) indicate the comparison between the same drugs in different periods (48 vs. 96). Bars indicate mean +- SD, n = 3, ***/^^^ p < 0.001, **/^^ p < 0.01, */^ p < 0.05, no indication-no statistical significance.
