  • FC experiment of A431 using 84135-4-RR (same clone as 84135-4-PBS)

    FC experiment of A431 using 84135-4-RR (same clone as 84135-4-PBS)

    1x10^6 A431 cells were intracellularly stained with 0.25 ug NELF-B Recombinant antibody (84135-4-RR, Clone:241434F12) and APC-Conjugated Goat Anti-Rabbit IgG(H+L)(red), or 0.25 ug Isotype Control (blue). Cells were fixed and permeabilized with True-Nuclear Transcription Factor Buffer Set. This data was developed using the same antibody clone with 84135-4-PBS in a different storage buffer formulation.

  • WB analysis using 84135-4-RR (same clone as 84135-4-PBS)

    WB analysis using 84135-4-RR (same clone as 84135-4-PBS)

    Various lysates were subjected to SDS PAGE followed by western blot with 84135-4-RR (NELF-B antibody) at dilution of 1:10000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 84135-4-PBS in a different storage buffer formulation.

  • IF Staining of A431 using 84135-4-RR (same clone as 84135-4-PBS)

    IF Staining of A431 using 84135-4-RR (same clone as 84135-4-PBS)

    Immunofluorescent analysis of (4% PFA) fixed A431 cells using NELF-B antibody (84135-4-RR, Clone: 241434F12 ) at dilution of 1:400 and CoraLite®488-Conjugated Goat Anti-Rabbit IgG(H+L) (SA00013-2), CL594-Phalloidin (red). This data was developed using the same antibody clone with 84135-4-PBS in a different storage buffer formulation.

  • FC experiment of BxPC-3 using 84135-4-RR (same clone as 84135-4-PBS)

    FC experiment of BxPC-3 using 84135-4-RR (same clone as 84135-4-PBS)

    1x10^6 BxPC-3 cells were intracellularly stained with 0.25 ug NELF-B Recombinant antibody (84135-4-RR, Clone:241434F12) and APC-Conjugated Goat Anti-Rabbit IgG(H+L)(red), or 0.25 ug Isotype Control (blue). Cells were fixed and permeabilized with True-Nuclear Transcription Factor Buffer Set. This data was developed using the same antibody clone with 84135-4-PBS in a different storage buffer formulation.

产品信息

84135-4-PBS targets NELFB as part of a matched antibody pair:

MP01055-1: 84135-4-PBS capture and 84135-1-PBS detection (validated in Cytometric bead array)

MP01055-3: 84135-4-PBS capture and 84135-3-PBS detection (validated in Cytometric bead array)

Unconjugated rabbit recombinant monoclonal antibody in PBS only (BSA and azide free) storage buffer at a concentration of 1 mg/mL, ready for conjugation. Created using Proteintech’s proprietary in-house recombinant technology. Recombinant production enables unrivalled batch-to-batch consistency, easy scale-up, and future security of supply.

This conjugation ready format makes antibodies ideal for use in many applications including: ELISAs, multiplex assays requiring matched pairs, mass cytometry, and multiplex imaging applications.Antibody use should be optimized by the end user for each application and assay.

背景介绍

Cofactor of BRCA1 (COBRA1) was first identified as a BRCA1-interacting protein and subsequently found to be the B subunit of the negative elongation factor complex (NELF-B). Cobra1 is essential for early embryogenesis (PMID: 19340312). The MW of this protein is 66 kDa, and this antibody specially recognises the 66 kDa protein.
