Slide Meiosis (Set of 12)
Product Code : SCL-BLE-11875
The StemAids 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. Manufactured to ISO 9001:2015 standards, 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
- Interphase: DNA replication and cell preparation.
- Leptotene: Initial chromatin condensation.
- Zygotene: Synapsis of homologous chromosomes.
- Pachytene: Crossing over becomes evident.
- Diplotene: Chiasmata visualization.
- Diakinesis: Nuclear envelope breakdown.
- Metaphase I: Homologous pairs align at the equator.
- Anaphase I: Separation of homologous chromosomes to opposite poles.
- Telophase I: Formation of two haploid nuclei.
- Metaphase II: Sister chromatids align at the equator.
- Anaphase II: Centromeres split; sister chromatids move to poles.
- Telophase II: Formation of four unique haploid daughter cells.
International Logistics & Compliance
StemAids 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 StemAids 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.
