Human Kidney Cell A498 based Proliferation Assay Service
Creative Biolabs' service is meticulously designed to provide the specific, actionable data required to advance your renal cell carcinoma (RCC) drug candidate. We go beyond simple cell counting to deliver a complete picture of your compound's mechanism of action (MOA). Our platform provides quantitative evidence distinguishing between growth inhibition concentration 50% (GI50) and lethal concentration 50% (LC50), confirms cell cycle arrest patterns, and identifies the induction of apoptosis (e.g., via caspase activation). This comprehensive data package ensures you have the therapeutic potential insights necessary to confidently de-risk your RCC development pipeline.
The A498 Cell Line: A Critical Model for RCC
The A498 cell line is a gold-standard in vitro model for clear cell RCC (ccRCC), critically reflecting the disease's hallmark disrupted von Hippel-Lindau (VHL) function. Its robust, reproducible growth is ideal for reliable IC50 determination. The model is instrumental for deep mechanistic insight, capable of measuring diverse cell death (apoptosis/necrosis) and pathway modulation, including the Akt-mTOR cascade. Its sensitivity to combination and synergy testing (e.g., Amygdalin/SFN), coupled with its ability to induce distinct G0/G1 or G2/M cell cycle blocks, ensures high therapeutic predictability.
Specific Deliverables and Solutions
Precise Efficacy Quantification
We deliver accurate GI50 and LC50 values for your compound, clearly distinguishing between agents that merely halt growth (GI50) and those that actively kill cancer cells (LC50). This is crucial for pipeline prioritization.
Confidence in Data
Every result is validated against a gold-standard reference inhibitor (staurosporine), ensuring the biological responsiveness and high fidelity of your data package.
Mechanism of Action Confirmation
By leveraging the A498 line's known genetics (VHL disruption), we provide context for how your drug affects fundamental RCC pathways (e.g., Akt/mTOR signaling or cell cycle modulation).
Synergy and Combination Testing
Our platform is optimized to test drug combinations, confirming synergistic activity with statistical rigor (e.g., bliss independence model), which is essential for next-generation multi-therapy approaches.

Workflow: Clear Steps for Reliable Proliferation Data
Our systematic, methodical workflow ensures full transparency and delivers the reproducible, high-quality data you need—providing the precision you can trust for critical decisions in your oncology program.
Publication
This study investigates Shikonin, a natural naphthoquinone, as a potent therapeutic agent against RCC using A-498 and CAKI-2 cell lines. Shikonin significantly inhibits proliferation and colony formation with superior potency compared to Sunitinib. Its cytotoxic effect is primarily mediated by apoptosis induction, evidenced by caspase-3/7 activation and PARP cleavage. Mechanistically, shikonin acts through multifaceted signaling modulation, including Ras/MAPK and PI3 K/AKT activation, NF-κB downregulation, and Bcl-2/PTEN alteration, highlighting its potential to overcome drug resistance in RCC.

FAQs
Q: Why use the A498 line over other RCC models like Caki-1 or 786-O?
A: While Creative Biolabs can adapt protocols for other lines, A498 is specifically favored for its disrupted VHL function, which mimics the genetic signature of the most common RCC subtype (ccRCC). This makes the results highly relevant to clinical translation.
Q: Is the luminescence detection method prone to compound interference?
A: Our scientists employ rigorous counter-screens and controls during assay validation to identify and mitigate any compound interference with the luminescence signal. We always ensure the signal we measure is directly due to viable cellular ATP, guaranteeing the fidelity of your final data.
Q: Can I combine this assay with a metastatic potential screening?
A: Yes, for a complete profile, we highly recommend complementing this service with our transwell invasion assays. You can achieve a comprehensive mechanism of action profile by evaluating both proliferation and invasive potential.
