How do your JAK1 phosphorylation assays differ from total JAK1 expression analysis?

Our JAK1 phosphorylation assays specifically measure the active, phosphorylated form of the JAK1 protein, which indicates its functional activation within a signaling pathway. In contrast, total JAK1 expression analysis quantifies the overall amount of JAK1 protein present, regardless of its activation state. Both types of assays are crucial, with phosphorylation assays revealing dynamic pathway activity and total expression providing context on protein abundance.

Can your services help in screening for selective JAK1 inhibitors?

Absolutely. Our services are specifically designed to support the identification and characterization of selective JAK1 inhibitors. We offer high-throughput kinase activity assays that can screen large compound libraries, followed by detailed mechanism of action studies and counter-screening against other JAK family members to ensure specificity and minimize off-target effects.

How do you ensure the specificity of your phospho-JAK1 antibodies?

The specificity of our phospho-JAK1 antibodies is rigorously validated through multiple orthogonal methods. This includes peptide blocking assays, phosphopeptide competition studies, and western blot analysis against lysates from cells treated with various inhibitors or activators to confirm their ability to exclusively recognize JAK1 when phosphorylated at the specified sites and not cross-react with other related kinases.

What kind of quality control measures do you have in place for JAK1 analysis?

We implement stringent quality control measures at every stage of the JAK1 analysis process. This includes using validated reagents, running appropriate positive and negative controls in every assay, performing replicate experiments to ensure reproducibility, and strictly adhering to standardized operating procedures. All instruments are regularly calibrated to ensure the highest level of data integrity.

Can your cell-based ELISA detect changes in JAK1 phosphorylation in real-time?

While our cell-based ELISA provides a sensitive snapshot of phospho-JAK1 levels directly within cells, it is typically an endpoint assay, meaning it measures phosphorylation at a specific time point after stimulation or treatment. For real-time kinetic analysis of phosphorylation changes, other techniques like live-cell imaging coupled with fluorescent reporters might be more suitable, which we can also discuss as part of a broader study design.

Is your JAK1 analysis service suitable for clinical sample analysis?

Our JAK1 analysis services are primarily tailored for preclinical research and drug discovery phases. While the robust nature of our assays can generate high-quality data from patient samples, it is important to note that our services are currently for research use only and are not intended for diagnostic purposes or for generating data for direct clinical decision-making without further validation in a GLP/GCP-compliant setting.

We offer a variety of strategic options designed to help our clients thoroughly understand JAK1's intricate roles in disease pathways, thereby accelerating their therapeutic development and lead discovery.

Introduction of JAK1

JAK1, a pivotal non-receptor tyrosine kinase, is crucial in autoimmune diseases and malignancies, acting as a central hub for cytokine signaling. It significantly influences metastatic cancer progression and mediates oncogenic STAT3 activation in mammary cancer cells. Intriguingly, JAK1 exhibits a dual role as either an oncogene or a tumor suppressor depending on context, making this intricate duality paramount for targeted therapeutic strategies.

JAK1 Inhibitor

JAK1 modulates key proinflammatory cytokines within the expansive JAK-STAT pathway, making its selective inhibition a potent therapeutic strategy for immune-mediated diseases. Importantly, JAK1 loss-of-function mutations can impair T cell recognition of tumor cells, contributing to PD-1 inhibitor resistance. Upon ligand binding, JAK1 self-phosphorylates and phosphorylates associated receptors, creating binding sites for signaling proteins. This fundamental link between cytokine receptors and downstream effectors drives the demand for efficient study methods.
