Lactate dehydrogenase A (LDHA) mediates interconversion of pyruvate and lactate, and increased lactate turnover is exhibited by malignant and infected immune cells. Hypoxic lung granuloma in Mycobacterium tuberculosis-infected animals present elevated levels of Ldha and lactate. Such alterations in the

Is this pen suitable to contain a drop of 3% H2O2 in methanol solution? Could the circle be erased by methanol?
1 answer-
Yes, this product is resistant to most organic solvents and would not be affected by exposure to methanol. However, the barrier may be dissolved by xylene.

Hi, I have slide with 4x5 tissue spots of 5 mm size each. I like to draw hydrophobic barrier line to protect each tissue spots by drawing a column or row or grid. Therefore, i would require a fine tip Pap pen. Is 2 mm tip good or 1 mm will be better.
1 answer-
The advanced PAP Pen is commonly used to create hydrophobic barriers on slides for various laboratory applications. It is often used to outline areas and draw boundaries to prevent mixing of reagents or solutions. Regarding the tip size, it depends on the specific requirements and preferences of the end-user. Both 2 mm and 1 mm tips can be suitable for creating hydrophobic barriers of the desired size on your slides. The choice between the two will depend on factors such as the precision needed by the end-user, the desired thickness or width of the barrier, and the personal experience and comfort with using different tip sizes of the end-user's.
If a finer and more precise line is required, a 1 mm tip may be preferable. However, if a slightly wider or more visible barrier line is needed, the 2 mm tip can be suitable.

Does this pen marking autofluorese?
1 answer-
This pen is suitable for use with fluorescent antibodies. It is not specifically tested for autofluorescence; no reports or complaints of this occurring have been filed. This PAP Pen Liquid Blocker, is a hydrophobic slide marker for staining procedures, creates a visible hydrophobic barrier that provides proper surface tension to hold reagents within a targeted area when applied around tissue sections or smears on a microscopic slide. This surface tension ensures the amount of reagent needed for sufficient reaction is reduced and retained for complete tissue section coverage. Multiple specimens can be separated by drawn circles or lines applied to the same slide.
PAP Pen Liquid Blockers contain a unique formulation that is water repellent, insoluble in alcohol and acetone, soluble in xylene and temperature resistant up to 120°C.
