PRPS2 Antibody, FITC conjugated

What is PRPS2 and why is it a significant research target?

PRPS2 (phosphoribosyl pyrophosphate synthetase 2) is an enzyme that plays crucial roles in nucleotide synthesis pathways and has been identified as an oncogene in several cancer types, including lung cancer. Recent research has revealed PRPS2's significant involvement in modulating the tumor microenvironment through regulation of immune cell recruitment and function. Specifically, PRPS2 has been shown to regulate the chemotaxis of tumor-associated macrophages (TAMs) and myeloid-derived suppressor cells (MDSCs) in tumor cells . This regulatory function makes PRPS2 an important target for cancer research, particularly in understanding tumor-immune interactions and developing potential therapeutic strategies.

What are the key characteristics of FITC-conjugated PRPS2 antibodies?

FITC-conjugated PRPS2 antibodies typically consist of anti-PRPS2 antibodies chemically linked to fluorescein isothiocyanate, creating a fluorescent probe that emits green light when excited at appropriate wavelengths. The commercially available FITC-conjugated PRPS2 antibodies often target specific amino acid sequences within the PRPS2 protein. For example, one commercially available antibody (ABIN7168162) targets amino acids 11-106 of the human PRPS2 protein . These antibodies are typically developed in rabbit hosts as polyclonal antibodies and purified using Protein G affinity purification to achieve >95% purity . The fluorescent conjugation enables visualization of PRPS2 expression and localization in various experimental settings without requiring secondary antibody staining steps.

What basic applications are FITC-conjugated PRPS2 antibodies suitable for?

FITC-conjugated PRPS2 antibodies are suitable for multiple fluorescence-based applications in research settings:

• Flow cytometry: For quantitative assessment of PRPS2 expression in cell populations

• Immunofluorescence (IF): For visualizing cellular localization of PRPS2

• Immunocytochemistry (ICC): For detection in cultured cells

• Fluorescence microscopy: For qualitative assessment of protein expression patterns

These applications are particularly valuable for studying PRPS2 in the context of tumor microenvironment research, where visualization of PRPS2-expressing cells in relation to immune cell populations can provide important insights into tumor-immune interactions .

What controls should be included when using FITC-conjugated PRPS2 antibodies in flow cytometry?

For rigorous flow cytometry experiments using FITC-conjugated PRPS2 antibodies, researchers should include:

• Isotype control: A FITC-conjugated IgG from the same host species (e.g., rabbit IgG-FITC) at the same concentration as the PRPS2 antibody to assess non-specific binding.

• Negative cell controls: Cell lines known not to express PRPS2 or cells where PRPS2 has been knocked down using siRNA/shRNA approaches, similar to the LLC-shPRPS2 cells described in the literature .

• Positive cell controls: Cell lines with confirmed PRPS2 expression, such as PRPS2-overexpressing cell lines (e.g., LLC-PRPS2 cells mentioned in the research) .

• Unstained controls: Cells with no antibody to establish autofluorescence baseline.

• Fluorescence minus one (FMO) controls: In multicolor panels, include all fluorochromes except FITC to properly set gates.

• Dead cell discrimination: Include a viability dye compatible with FITC to exclude non-specific binding to dead cells.

When analyzing results, the median fluorescence intensity (MFI) should be compared between experimental samples and controls to accurately quantify PRPS2 expression levels.

How should researchers optimize immunofluorescence protocols for FITC-conjugated PRPS2 antibodies?

To optimize immunofluorescence protocols using FITC-conjugated PRPS2 antibodies:

• Fixation optimization:

  • Test multiple fixatives (4% paraformaldehyde, methanol, acetone)

  • Determine optimal fixation duration (10-30 minutes)

  • For PRPS2, paraformaldehyde fixation is often suitable for preserving protein epitopes

• Permeabilization considerations:

  • Test detergents of varying strengths (0.1-0.5% Triton X-100, 0.01-0.1% saponin)

  • For intracellular PRPS2 detection, gentle permeabilization with 0.1% Triton X-100 is typically effective

• Blocking optimization:

  • Use serum from the same species as the secondary antibody (if any)

  • Include 1-5% BSA to reduce non-specific binding

  • Consider adding 0.1-0.3% glycine to quench free aldehyde groups after fixation

• Antibody titration:

  • Test antibody at multiple concentrations (1:50 to 1:1000)

  • Incubate at 4°C overnight or room temperature for 1-2 hours

• Signal preservation:

  • Mount with anti-fade media containing DAPI for nuclear counterstain

  • Protect from light and store at 4°C

  • Image promptly as FITC signal may deteriorate over time

• Confocal microscopy settings:

  • Excitation wavelength: ~495 nm

  • Emission collection: ~520 nm

  • Adjust gain and offset to prevent saturation while maximizing signal-to-noise ratio

These optimizations ensure specific detection of PRPS2 while minimizing background fluorescence and preserving the FITC signal.

What are the technical limitations of using FITC-conjugated antibodies in tissues with high autofluorescence?

When working with FITC-conjugated PRPS2 antibodies in tissues with high autofluorescence (such as liver, kidney, or lung cancer tissues), researchers face several technical challenges that require methodological solutions:

• Signal-to-noise ratio challenges:

  • FITC emits in the green spectrum (~520 nm), which overlaps with natural tissue autofluorescence

  • Particularly problematic in tissues containing lipofuscin, elastin, and collagen

• Methodological solutions for immunohistochemistry:

  Autofluorescence Reduction Method	Protocol Details	Advantages	Limitations
  Sudan Black B treatment	0.1-0.3% in 70% ethanol for 20 minutes	Effective for lipofuscin	May reduce specific signal slightly
  Sodium borohydride treatment	0.1% solution for 2-3 minutes	Quenches aldehyde-induced fluorescence	Short shelf-life, must be freshly prepared
  Commercial autofluorescence quenchers	According to manufacturer instructions	Ready-to-use, standardized	Higher cost
  Photobleaching	Pre-exposure to light source	Simple, no additional reagents	Time-consuming, may damage tissue
  Spectral unmixing	Acquisition of full emission spectra	Digital removal of autofluorescence	Requires specialized equipment

• Alternative detection strategies:

  • Consider switching to antibodies conjugated to fluorophores in red/far-red spectrum

  • Use amplification systems like tyramide signal amplification (TSA)
