PSMB5 Antibody in Immunocytochemistry (ICC/IF)

FIGURE: 1 / 14

PSMB5 Antibody (PA1-977) in ICC/IF

Immunofluorescence analysis of PSMB5 was performed using 70% confluent log phase DU 145 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with PSMB5 Polyclonal Antibody (Product # PA1-977) at 1:100 dilution in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A327...

PSMB5 Antibody — Figure 5 ( a ) Immunoblots of proteasome catalytic subunits in H727 cells transfected with siRNA targeting beta5, beta2 or beta5i. ( b ) The catalytic activity of beta5 subunit was decreased in H727 cells transfected with siRNA targeting beta5 compared with H727 cells transfected with scrambled siRNA. ( c ) Effects of siRNA knockdown of beta5, beta5i, or beta2 on Cfz sensitivity (IC 50 values) in H23 and H727 cells. Data are shown as mean +- SD derived from a single non-linear regression based on n = 3 replicates per compound per concentration. ( d ) Heat map showing proteasome catalytic subunit activity profiles of 6 PI-naive patient MM samples purchased from Conversant Biologics and AllCells (left). The numbers represent hydrolysis rates of respective substrates (RFU/min, mean values derived from three technical replicates) and were converted to color format and clustered by using the program ""R"" ( http://www.R-project.org ) (left panel). Carfilzomib (Cfz) cell viability of the same 6 patient MM cells was measured via CellTiter-Glo Luminescent Cell Viability Assay (right panel). {KD}

Product Specific Information

PA1-977 detects proteasome 20S X from bovine, mouse and human samples.

PA1-977 has been successfully used in Western blot and ICC/IF procedures. By Western blot, this antibody detects an ~23 kDa protein representing proteasome 20S X.

The PA1-977 immunizing peptide corresponds to amino acid residues 243-259 from mouse proteasome 20S X. This sequence is 94% conserved in human and rat. PA1-977 immunizing peptide (Cat. # PEP-172) is available for use in neutralization and control procedures.

Target Information

Cyclic nucleotide phosphodiesterases.
