2025
This video demonstrates a technique for nucleic acid extraction from whole human blood using magnetic glass particles (MGPs) — small magnetic beads coated with silica. Upon lysing the blood cells using a lysis buffer, the released nucleic acids bind to the surface of silica-coated MGPs, extracting the molecules from the sample.

Introduction to Serological Pipettes and Pipettors

2023
The serological pipette is frequently used in the laboratory for transferring milliliter volumes of liquid, from less than 1 ml to up to 50 ml. The pipettes can be sterile, plastic, and disposable or sterilizable, glass and reusable. Both kinds of pipettes use a pipet-aid, for the aspiration and dispensation of liquids. Different sizes of pipettes can be used with the same pipet-aid for a variety of experimental assays. For example, serological pipettes are useful for mixing chemical solutions...

The Looking Glass Self

The concept of the looking-glass self describes how an individual's self-concept is shaped by their perception of how others see them. This psychological theory, first introduced by sociologist Charles Horton Cooley in 1902, posits that self-identity emerges in a social context and is influenced by the judgments—real or imagined—of others.Research suggests that individuals frequently overestimate how positively others perceive them. This is particularly evident in physical self-perception,...

FAQs
Successful extraction depends on matching the pipette’s narrow opening and movement to the target material. Gentle suction or pressure draws the selected cell or fragment into the tip, while movement at the boundary helps separate it from neighboring material. Microscopic observation guides this interaction, allowing the operator to distinguish the target from surrounding sample during recovery.
Unlike bulk recovery methods, this approach addresses biological material at the level of individual cells, tissue fragments, or specimens. That scale reduces the chance of mixing distinct components and supports preservation of structural organization. The advantage matters when later analysis requires a defined biological unit rather than a pooled sample containing material from multiple sources.
Mechanical control is central to the outcome. Excessive force or poorly controlled movement could compromise the material being recovered, whereas gentle suction or pressure and deliberate positioning support intact collection. The finely drawn tip provides physical selectivity, and the microscope supplies visual feedback for adjusting contact with the target and its surroundings.
A typical workflow begins by locating the desired cell, fragment, or specimen under a microscope. The glass pipette is then positioned near the target, and controlled suction or pressure brings the material into the tip. Careful movement separates it from adjacent sample material, after which the recovered specimen can be directed toward culture, imaging, molecular assays, or transplantation studies.
The essential setup combines a finely drawn glass pipette with microscopic visualization and a means of applying controlled suction or pressure. The pipette supplies the narrow interface for selective handling, while the microscope supports accurate positioning and observation. Together, these elements enable micrometer-scale manipulation without relying on bulk processing that could mix biological components.
Researchers may choose glass pipette extraction when a sample contains neighboring biological components that must be handled separately. Recovered material can support cell isolation, embryo manipulation, tissue sampling, or individual-specimen recovery. Depending on the study, the isolated material may then be examined by imaging, maintained in culture, analyzed molecularly, or used in transplantation studies.
