Gram Positive and Gram Negative Cell Wall Model Manufacturer,Supplier and Exporter in India
Product Code : JC-BE-6171
The Gram Positive and Gram Negative Cell Wall Model from Jaincolab is a three-dimensional teaching model that contrasts the cell wall structure of Gram-positive and Gram-negative bacteria.
It is used in microbiology courses to explain the structural basis of the Gram stain reaction and its relevance to bacterial classification and antibiotic action.
What the Concept States
| Parameter | Details |
|---|---|
| Gram-Positive Cell Wall | A thick peptidoglycan layer interspersed with teichoic acids retains the crystal violet-iodine complex during Gram staining |
| Gram-Negative Cell Wall | A thin peptidoglycan layer sandwiched between the plasma membrane and an outer membrane containing lipopolysaccharide (LPS) |
| Outer Membrane | Present only in Gram-negative bacteria; contains LPS, porins, and contributes to endotoxin activity |
| Gram Stain Outcome | Gram-positive cells stain purple/violet; Gram-negative cells stain pink/red after counterstaining with safranin |
| Clinical Relevance | Cell wall differences influence antibiotic susceptibility, such as penicillin sensitivity in many Gram-positive bacteria |
Key Features
- Contrasts Gram-positive and Gram-negative bacterial cell wall structure side by side
- Shows the role of peptidoglycan thickness and the outer membrane in the Gram reaction
- Explains the structural basis of Gram staining results
- Durable, exam-oriented construction for repeated classroom use
- Compact benchtop format suitable for laboratories and lecture halls

Frequently Asked Questions
Q1. What does the Gram Positive and Gram Negative Cell Wall Model demonstrate?
A. It demonstrates the structural differences between Gram-positive and Gram-negative bacterial cell walls.
Q2. What makes a bacterium Gram-positive?
A. A thick peptidoglycan layer with teichoic acids retains the crystal violet stain, making the bacterium Gram-positive.
Q3. What makes a bacterium Gram-negative?
A. A thin peptidoglycan layer and an outer membrane containing lipopolysaccharide cause the crystal violet stain to wash out, making the bacterium Gram-negative.
Q4. Why is the outer membrane significant in Gram-negative bacteria?
A. It contains lipopolysaccharide, which acts as an endotoxin and contributes to antibiotic resistance.
Q5. Who uses this model?
A. Microbiology, medical, and pharmacy students and faculty use it to study bacterial cell wall structure.
