At times, your system may display an error indicating the need to correct histological spots. There can be several reasons for this problem.
Nuclear staining errors.Poor eosin differentiation.Poor contrast between hematoxylin and total eosin.The seeds are reddish brown.Dark sediment on a glass slide.Uneven coloration.White spots on slides after dewaxing.Removes fabric stains after moisturizing.
While hematoxylin and eosin staining is indeed a relatively easy staining to achieve, there are many artifacts at this stage that will certainly affect good staining. Can items be attributed to different reasons?
Excessive staining occurs due to overuse of the signal in the sample. This encourages the sample to become saturated, thereby reducing large differences. Overly colored swatches may appear washed out, washed out, or possibly monochrome.

Division plays an important role in obtaining high quality stains. Thick and thin cuts, crackles, fabric that “explodes” and swimmers in the water are sure to bathe any cut artifacts that could negatively affect how the fabric absorbs the stain.

Thick and thin cuts are almost always the result of improper technique, especially at the cutting station due to uneven rotation of the microtome. Many laboratories are now taking advantage of automated microtome cutting not only to reduce ergonomic trauma, but also to securely deliver slides.

Growing chatter and cuts are usually associated with fabric handling, rattling is the result of an explosion of overworked / overdried tissue, and cuts are the result of using subcontracted tissue. / Poorly infiltrated too much tissue indicator Ref Abraded tissue can be easily detected when red blood cells (erythrocytes) are examined through the vessels.

Eosin may get into alcohol during staining. The water in xylene can, over time, cause most of the eosin to leak out of the tissue. He is caught on the slide like a pink insect. This artifact can occur even if xylene is not clearly contaminated water.

is never the only way to drink xylene. Humidity in the environment can increase the rate of water contamination of xylene.
What are the five stages of histological staining?
Histological staining is a series of engineering processes performed in preparing tissue samples by staining them with histological forms for easy reading under a microscope (Anderson, 2011). The histological staining process involves five main steps, which include: Fixing, preserving, coating, cutting, and staining (Titford, 2009).
Depending on the geographic location, the caliber of the water can be very different. Fluoridation, pH and other minerals present cannot directly affect how the dyes are absorbed into the fabric, but also the lifespan during dyeing. For example, because hematoxylin is considered slightly acidic, alkaline tap water in the house can raise the pH of my hematoxylin, making it less effective. When the usual water quality is poor or unstable, the demand for demineralized water (DI) is practically a good option. Remember to make sure the pressurized deionized water is sufficient for many of the dyeing machines on the platform.
Frozen specimens can be a serious staining problem. Timing is extremely important and teams are constantly advisedIt is necessary to shorten the staining time so that the pathologist can react quickly to the operating room personnel. However, it can be difficult to balance quality color and speed.
One of the most important artifacts I have professionally is uneven coloration, which has nothing to do with shoulder stiffness. The main reason is to fix and rinse the aged staining slide. Remember that marketing materials used to cut frozen tissue are water soluble and MUST be removed from the specimen, similar to removing paraffin from conventional specimens prior to staining. Multimedia can even prevent the penetration of paints like paraffin wax. And as in real life, you probably won’t see any trace of the medium on the slide if I say that the final coloration is done when steps of brown or reddish color remove the medium along the strategy.
