ZNF335 Antibody, HRP conjugated

What is ZNF335 and what are its key biological functions?

ZNF335 (Zinc finger protein 335), also known as NRC-interacting factor 1 (NIF-1), is a nuclear zinc finger protein that functions as a component or associated component of histone methyltransferase complexes. It regulates transcription by recruiting these complexes to gene promoters and enhances ligand-dependent transcriptional activation by nuclear hormone receptors. ZNF335 plays a crucial role in neural progenitor cell proliferation and self-renewal through the regulation of specific genes involved in brain development, including REST (RE1-Silencing Transcription factor). Additionally, it controls the expression of genes involved in somatic development and regulates processes such as lymphoblast proliferation . Research has identified ZNF335 as a causative gene for severe microcephaly, small somatic size, and neonatal death, establishing its essential role in neurogenesis and neuronal differentiation .

What are the structural characteristics of ZNF335 Antibody, HRP conjugated?

ZNF335 Antibody, HRP conjugated is a polyclonal antibody raised in rabbits against a recombinant fragment of human ZNF335 protein (amino acids 672-909). The antibody is conjugated to Horseradish Peroxidase (HRP), which facilitates direct detection without the need for secondary antibodies. It has an IgG isotype and is purified using Protein G affinity chromatography, achieving a purity of >95%. The antibody is supplied in liquid form in a storage buffer containing 50% glycerol, 0.01M PBS at pH 7.4, with 0.03% Proclin 300 as a preservative . This configuration makes it particularly suitable for ELISA applications where direct detection systems are preferred.

What is the difference between ZNF335 Antibody, HRP conjugated and non-conjugated ZNF335 antibodies?

The primary difference lies in their application workflow and detection methods. ZNF335 Antibody, HRP conjugated has horseradish peroxidase directly attached to the antibody, allowing for immediate enzymatic reaction with substrates to produce colorimetric, chemiluminescent, or fluorescent signals. This eliminates the need for a secondary antibody incubation step, streamlining the experimental procedure and potentially reducing non-specific background. In contrast, non-conjugated ZNF335 antibodies require a secondary detection step using labeled secondary antibodies that recognize the primary antibody. While the conjugated version offers workflow advantages in ELISA applications, non-conjugated antibodies provide more flexibility in detection methods and potential signal amplification through secondary antibody systems . When choosing between these formats, researchers should consider their specific experimental design, desired sensitivity, and available detection instruments.
