TCF7L1 Antibody, HRP conjugated

What is TCF7L1 and what cellular functions does it regulate?

TCF7L1 (Transcription factor 7-like 1) is a protein encoded by the TCF7L1 gene in humans, also known as TCF-3, TCF3, or HMG box transcription factor 3. This protein participates as a key mediator in the Wnt signaling pathway, functioning as a DNA-binding transcriptional regulator. TCF7L1 acts primarily as a repressor in the absence of β-catenin (CTNNB1) and converts to an activator when β-catenin is present . The protein is approximately 62.6 kilodaltons in mass and has orthologs in several species including canine, porcine, monkey, mouse, and rat .

From a functional perspective, TCF7L1 is necessary for critical developmental processes including:

• Terminal differentiation of epidermal cells

• Formation of keratohyalin granules

• Development of barrier function in the epidermis

• Down-regulation of NQO1, leading to increased mitomycin c resistance

Recent research has identified TCF7L1 as an essential factor in hypothalamo-pituitary axis development, where it functions as a transcriptional repressor regulating hypothalamic signals involved in pituitary formation .

What does HRP conjugation mean in the context of TCF7L1 antibodies and how does it enhance experimental applications?

HRP (Horseradish Peroxidase) conjugation refers to the covalent attachment of the enzyme horseradish peroxidase to an antibody targeting TCF7L1. This conjugation provides a direct detection system through enzymatic activity rather than requiring secondary antibody binding. When HRP encounters its substrate (typically TMB, DAB, or luminol-based reagents), it catalyzes a reaction producing colorimetric, chemiluminescent, or fluorescent signals.

The HRP conjugation offers several methodological advantages:

• Eliminates the need for secondary antibody incubation, reducing experimental time and potential cross-reactivity

• Provides enhanced sensitivity for detection of low-abundance proteins

• Enables direct quantification through enzymatic signal amplification

• Reduces background noise in assays like ELISA by eliminating non-specific binding from secondary antibodies

For TCF7L1 research specifically, HRP-conjugated antibodies (such as product code CSB-PA884626OB01HU) are optimized for ELISA applications where direct detection provides cleaner results for quantitative analysis of TCF7L1 expression levels .

What are the optimal conditions for using TCF7L1 Antibody, HRP conjugated in ELISA experiments?

When utilizing TCF7L1 Antibody, HRP conjugated (such as CSB-PA884626OB01HU) for ELISA applications, the following optimized protocol parameters are recommended:
