Validation Data Gallery

Filter:
  • Western Blot (WB) analysis of various lysates using BBS4 Recombinant antibody (82961-1-RR)

    WB analysis using 82961-1-RR (same clone as 82961-1-PBS)

    Various lysates were subjected to SDS PAGE followed by western blot with 82961-1-RR (BBS4 antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 82961-1-PBS in a different storage buffer formulation.

  • Western Blot (WB) analysis of HEK-293 cells using BBS4 Recombinant antibody (82961-1-RR)

    WB analysis of HEK-293 using 82961-1-RR (same clone as 82961-1-PBS)

    WB result of BBS4 antibody (82961-1-RR; 1:1200; incubated at room temperature for 1.5 hours) with sh-Control and sh-BBS4 transfected HEK-293 cells. This data was developed using the same antibody clone with 82961-1-PBS in a different storage buffer formulation.

  • Immunofluorescence (IF) / fluorescent staining of hTERT-RPE1 cells using BBS4 Recombinant antibody (82961-1-RR)

    IF Staining of hTERT-RPE1 using 82961-1-RR (same clone as 82961-1-PBS)

    Immunofluorescent analysis of (4% PFA) fixed hTERT-RPE1 cells using BBS4 antibody (82961-1-RR, Clone: 230303C2 ) at dilution of 1:1000 and CoraLite®488-Conjugated Goat Anti-Rabbit IgG(H+L) (SA00013-2), CoraLite®594 ARL13B antibody (CL594-17711, red). This data was developed using the same antibody clone with 82961-1-PBS in a different storage buffer formulation.

  • Flow cytometry (FC) experiment of HeLa cells using BBS4 Recombinant antibody (82961-1-RR)

    FC experiment of HeLa using 82961-1-RR (same clone as 82961-1-PBS)

    1x10^6 HeLa cells were intracellularly stained with 0.25 ug BBS4 Recombinant antibody (82961-1-RR, Clone:230303C2) and CoraLite®488-Conjugated Goat Anti-Rabbit IgG(H+L) (SA00013-2)(red), or 0.25 ug Isotype Control (blue). Cells were fixed with 4% PFA and permeabilized with Flow Cytometry Perm Buffer (PF00011-C). This data was developed using the same antibody clone with 82961-1-PBS in a different storage buffer formulation.

Background Information

BBS4 (Bardet-Biedl syndrome protein 4) is one of the early BBS proteins discovered, with 35 mutations reported to cause the BBS phenotype (PMID: 26762677). BBS4 undergoes localization to the centriolar satellites of centrosomes and basal body of primary cilia, where it takes part in recruiting cargo to centriolar satellites and allowing the formation of a functional centrosomal microtubule organizing center (MTOC) (PMID: 25860617). Some research has found that BBS4 expression in humans during the development of CNS and sensory organs, concerning the cardinal clinical signs of BBS (PMID: 33860840).
