Slide Meiosis (Set of 12)

Product Code : SCL-BLE-11875

The JLab India Meiosis Slide Set is a comprehensive histological collection engineered for the sequential study of reduction division in eukaryotes. This set features 12 professionally prepared microscope slides capturing the critical phases of Meiosis I and Meiosis II, typically sourced from high-activity tissues such as Onion (Allium) anthers or Lily (Lilium) pollen sacs. This set is an indispensable resource for University Genetics, Botany, and Cell Biology laboratories to quantify chromosomal behavior and genetic recombination.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)

• Genetic Interface: Facilitates student understanding of the transition from diploid (2n) to haploid (n) states, supporting the core study of inheritance and sexual reproduction.
• Chromosomal Quantification: Enables the identification of homologous pairs; learners apply high-power magnification to observe Prophase I (Pachytene/Diplotene) to visualize the physical evidence of crossing over.
• Division Analysis: Supports the analysis of "Independent Assortment"; students evaluate the alignment of chromosomes during Metaphase I and their subsequent segregation in Anaphase I.
• Gametogenesis Evaluation: Allows students to evaluate the resulting "Tetrad" of four genetically distinct daughter cells, fostering a deeper understanding of biological variation.

List of Stages Included in the Set

1. Interphase: DNA replication and cell preparation.
2. Leptotene: Initial chromatin condensation.
3. Zygotene: Synapsis of homologous chromosomes.
4. Pachytene: Crossing over becomes evident.
5. Diplotene: Chiasmata visualization.
6. Diakinesis: Nuclear envelope breakdown.
7. Metaphase I: Homologous pairs align at the equator.
8. Anaphase I: Separation of homologous chromosomes to opposite poles.
9. Telophase I: Formation of two haploid nuclei.
10. Metaphase II: Sister chromatids align at the equator.
11. Anaphase II: Centromeres split; sister chromatids move to poles.
12. Telophase II: Formation of four unique haploid daughter cells.

International Logistics & Compliance

JLab India ensures comprehensive OEM readiness for global institutional procurement:

• Packaging: Housed in a durable, indexed wooden or plastic slide box. Each slide is protected by individual slots to prevent surface contact and vibration damage during international transit.
• Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a detailed stage-identification guide for instructors.
• Durability: Fixed and dehydrated specimens are color-fast and resistant to degradation, ensuring the set remains a viable teaching tool for over 10 years when stored correctly.

Direct OEM Sourcing Advantages

Procuring the JLab India Meiosis Set directly ensures vertical manufacturing control:

• High Mitotic Index: We harvest tissues at the peak of reproductive activity to ensure that every slide contains a high density of cells in the specific target stage.
• Vivid Chromatin Contrast: Direct oversight of the staining process ensures that chromosomes are darkly stained against a clear cytoplasm, making "crossing over" points visible even to novice students.
• Direct Factory Inventory: Guaranteed availability of complete sets or individual replacement slides to maintain institutional laboratory kits.
• Quality Assurance: Every slide is verified by a cytogeneticist to ensure that the morphological markers of the specific meiotic stage are clearly identifiable and free from artifacts.
