Microscope Slide - Spirogyra Conjugation Individually packed in PP slide mailer

This prepared microscope slide of Spirogyra conjugation comes individually packed in a PP slide mailer. It's made using professional biological sectioning techniques, with every step carefully controlled, from collecting and fixing the sample to dehydration, embedding, sectioning, staining and mounting.

The slide features a specimen of Spirogyra undergoing conjugation, a process of sexual reproduction in this filamentous green alga. The slide provides an opportunity to observe the alignment of filaments and formation of conjugation tubes where genetic material is exchanged between cells.

Use in Education

Suitable for general biology, botany, and microbiology courses, this slide can be used in classroom demonstrations and laboratory exercises focused on algal reproduction and life cycles. It supports lessons on sexual reproduction in algae, cellular interactions, and genetic exchange. Students can use the slide to practise microscope techniques while observing the structural details of Spirogyra filaments during conjugation.

How the Slides Are Made

• Raw material: Only fresh, undamaged biological tissue is selected, so the sections are authentic and scientifically accurate.
• Preservation: Professional fixatives preserve the samples quickly, so the tissue cells don't deform or deteriorate. The tissue then goes through graded dehydration, clearing and wax infiltration, which gives it an even texture and the right hardness for sectioning. Each step is carefully timed and uses controlled reagent concentrations.
• Sectioning: High-precision sectioning machines, adjusted by experienced technicians, give an even section thickness with no wrinkles or damage. Sections are usually 5 to 10µm thick.
• Staining and mounting: Classic methods such as haematoxylin and eosin (H&E) staining, carefully timed, give clear contrast between nucleus and cytoplasm and clear colours. A high-transparency resin bonds the section to the slide and cover glass, keeping out moisture and oxidation, so the slide can be stored and reused for a long time without the colours fading or the section lifting.
• Please note that the steps may vary depending on the specimen.

Useful Slide Abbreviations

• T.S. or C.S. = transverse or cross section: a thin slice across the organism or tissue.
• L.S. = longitudinal section: a slice along the length of the organism.
• C.S. & L.S. = cross and longitudinal sections on the same slide for comparison.
• W.M. = whole mount: the entire organism or structure is mounted on the slide.
