PRKAA1 Antibody, Biotin conjugated

What is PRKAA1 and what biological roles does it serve in cellular metabolism?

PRKAA1 (Protein Kinase AMP-Activated Catalytic Subunit Alpha 1) functions as the catalytic subunit of AMP-activated protein kinase (AMPK), a critical energy sensor that regulates cellular energy metabolism. The protein serves as a central metabolic switch that responds to reductions in intracellular ATP levels by activating energy-producing pathways while simultaneously inhibiting energy-consuming processes. This includes inhibition of protein, carbohydrate, and lipid biosynthesis, as well as regulation of cell growth and proliferation . PRKAA1 exerts its effects through direct phosphorylation of metabolic enzymes and through longer-term effects via phosphorylation of transcription regulators . The protein is also known by several aliases including 5'-AMP-activated protein kinase catalytic subunit alpha-1, AMPK subunit alpha-1, and AMPK1 .

PRKAA1 plays crucial roles in multiple metabolic pathways:

• Lipid metabolism regulation through phosphorylation of enzymes like ACACA, ACACB, and LIPE

• Insulin signaling and glycolysis regulation

• Cellular polarity regulation through remodeling of the actin cytoskeleton

• Fatty acid and cholesterol synthesis modulation

• Enzyme-Linked Immunosorbent Assay (ELISA): The biotin conjugation enhances detection sensitivity in immunoassays, allowing for robust quantification of PRKAA1 in complex biological samples .

• Immunohistochemistry on paraffin-embedded tissues (IHC-P): The antibody enables visualization of PRKAA1 expression patterns in tissue sections, providing spatial information about protein localization .

• Immunohistochemistry on frozen tissues (IHC-F): For tissues where paraffin embedding may compromise epitope integrity, the antibody can be used on frozen sections to maintain antigen recognition .

While Western blotting is not specifically mentioned for the biotin-conjugated version in the search results, polyclonal antibodies against PRKAA1 are generally suitable for this application as well, allowing researchers to detect and quantify the protein in cell or tissue lysates .

What are the optimal storage and handling conditions for PRKAA1 Antibody, Biotin conjugated?

Proper storage and handling of PRKAA1 Antibody, Biotin conjugated is essential for maintaining its functionality and specificity over time. The recommended storage conditions include:

• Temperature: Store at -20°C or -80°C upon receipt .

• Avoid repeated freeze-thaw cycles, as this can compromise antibody integrity and performance .

• Long-term storage: The antibody can be stored at -20°C for up to 12 months under proper conditions .

The antibody is typically supplied in a storage buffer containing preservatives and stabilizers:

• 50% Glycerol solution with 0.01M PBS, pH 7.4, and 0.03% Proclin 300 as a preservative .

• Alternative formulation may include 0.01M TBS (pH 7.4) with 1% BSA, 0.03% Proclin300, and 50% Glycerol .

These buffer components help maintain antibody stability and prevent microbial contamination during storage. For optimal performance, it's recommended to aliquot the antibody upon first thaw to minimize freeze-thaw cycles and preserve activity.

What species reactivity does PRKAA1 Antibody, Biotin conjugated exhibit?

Understanding the species reactivity of PRKAA1 Antibody, Biotin conjugated is crucial for experimental design and interpretation. Based on the provided search results, the species reactivity varies depending on the specific antibody product:

This variation in species reactivity is important to consider when selecting an antibody for your research. The Cusabio product (CSB-PA618759LD01HU) is specifically designed for human samples, having been developed using a recombinant human PRKAA1 protein fragment (amino acids 325-543) . In contrast, the Bioss product (bs-12972R-Biotin) is developed for mouse samples, with predicted cross-reactivity to rat samples .

Researchers should carefully match the antibody's species reactivity to their experimental model to ensure specific and reliable detection of the target protein.

How can phospho-specific PRKAA1 antibodies be used to monitor AMPK activation states?

Phospho-specific antibodies targeting PRKAA1 provide powerful tools for monitoring the activation state of AMPK in various physiological and pathological conditions. AMPK activation is primarily regulated by phosphorylation at specific residues, particularly Thr183 in AMPK alpha 1 (corresponding to Thr172 in AMPK alpha 2) .

Methodological approach for studying AMPK activation:

• Baseline assessment: Establish normal phosphorylation levels in your model system using a combination of total PRKAA1 antibody and phospho-specific antibody (such as anti-AMPK alpha 1 phospho Ser496 or phospho Thr183) .

• Treatment conditions: Subject cells or tissues to conditions known to alter AMPK activity, such as:

  • Glucose deprivation or 2-deoxyglucose treatment to increase AMP:ATP ratio

  • AICAR (5-aminoimidazole-4-carboxamide ribonucleotide) treatment to directly activate AMPK

  • Metformin treatment to indirectly activate AMPK

  • Compound C to inhibit AMPK activity

• Multiplex analysis: Utilize the biotin conjugation for multiplexed detection with other signaling markers. This can be achieved through:

  • Dual immunofluorescence using streptavidin-conjugated fluorophores

  • Sequential immunohistochemistry on tissue sections

  • Flow cytometry for cell-by-cell analysis of phosphorylation states

• Quantitative assessment: Measure the ratio of phosphorylated PRKAA1 to total PRKAA1 to determine the activation state, rather than simply measuring phospho-PRKAA1 levels alone.

This approach allows researchers to monitor AMPK activation dynamics in response to various metabolic stresses, pharmacological interventions, or pathological conditions, providing insight into the regulation of energy homeostasis in different physiological contexts.

What are potential cross-reactivity concerns when using PRKAA1 Antibody, Biotin conjugated?

Cross-reactivity is a significant concern when working with antibodies targeting PRKAA1, primarily due to the high sequence homology between AMPK alpha 1 (PRKAA1) and AMPK alpha 2 (PRKAA2) subunits. Researchers should consider several factors to address potential cross-reactivity issues:

• Sequence homology analysis: PRKAA1 and PRKAA2 share significant sequence similarity, particularly in functional domains. Antibodies raised against conserved regions may detect both isoforms, while those targeting unique regions are more likely to be isoform-specific .

• Epitope consideration: The specificity of an antibody is determined by the epitope it recognizes. For PRKAA1 antibodies:

  • The Cusabio antibody (CSB-PA618759LD01HU) is raised against amino acids 325-543 of human PRKAA1 .

  • The Bioss antibody (bs-12972R-Biotin) targets the region around phosphorylation site Ser496 in mouse PRKAA1 .

• Validation controls:

  • Positive controls: Use samples with known expression of PRKAA1 (e.g., liver tissue).

  • Negative controls: Consider tissues with low PRKAA1 expression or use PRKAA1 knockout models.

  • Peptide competition assays: Pre-incubation with the immunizing peptide should abolish specific binding.

  • Isoform comparison: Test reactivity against recombinant PRKAA1 and PRKAA2 proteins to assess cross-reactivity.

• Technical considerations:

  • Optimize antibody concentration to minimize non-specific binding.

  • Include appropriate blocking steps to reduce background.

  • Consider using more stringent washing conditions to eliminate weak cross-reactive binding.

By addressing these concerns systematically, researchers can ensure that their results accurately reflect PRKAA1-specific signals rather than cross-reactivity with other AMPK subunits or unrelated proteins.

How does biotin conjugation affect the performance of PRKAA1 antibodies in different experimental systems?

Biotin conjugation of PRKAA1 antibodies offers several advantages and considerations for experimental applications, impacting both sensitivity and experimental design:
