T-cell leukemia/lymphoma protein 1A (TCL1) is a member of the TCL1 family and enhances the phosphorylation and activation of AKT1, AKT2 and AKT3. TCL1 promotes the nuclear translocation of AKT1 and enhances cell proliferation, stabilizes mitochondrial membrane potential and promotes cell survival. The expression of TCL1 is restricted to lymphoid cells. It is expressed early in lymphocyte differentiation. Strong expression of TCL1 is found in a subset of mantle zone B lymphocytes and is expressed to a lesser extent by follicle center cells. In B-cell neoplasia, TCL1 immunoreactivity is found in the majority of B-cell lymphomas including lymphoblastic lymphoma, chronic lymphocytic leukemia, mantle cell lymphoma, follicular lymphoma, Burkitt lymphoma, diffuse large B-cell lymphoma (60%), and primary cutaneous B-cell lymphoma (55%). The expression of the TCL1 gene characterizes low-grade B-cell lymphomas.

Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA721207) at 1/1,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature.
Application: Immunohistochemistry (IHC-P)
Species: Human Tissue: Tonsil Sample: Paraffin-embedded section
Wash buffer: 1× TBST Endogenous peroxidase blocking: 3% H₂O₂, 10 minutes at room temperature. Blocking: 1% BSA + 10% normal goat serum, 10 minutes at room temperature. Primary antibody: HA721207, 1/30,000, 1 hour at room temperature. Secondary antibody: HA1119, 20 minutes at room temperature.
Immunocytochemistry analysis of PC-3 cells labeling Tcl1 with Rabbit anti-Tcl1 antibody (HA721207) at 1/50 dilution.
Cells were fixed in 4% paraformaldehyde for 10 minutes at 37 ℃, permeabilized with 0.05% Triton X-100 in PBS for 20 minutes, and then blocked with 2% negative goat serum for 30 minutes at room temperature. Cells were then incubated with Rabbit anti-Tcl1 antibody (HA721207) at 1/50 dilution in 2% negative goat serum overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488, HA1121) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI.
Flow cytometric analysis of Daudi cells labeling Tcl1.
Cells were fixed and permeabilized. Then stained with the primary antibody (HA721207, 1ug/ml) (red) compared with Rabbit IgG Isotype Control (green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Rabbit IgG Secondary antibody (HA1121) at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
