When the Gill No 1 hematoxylin is first poured from the bottle, the solution appears as a dark reddish-purple color. If the nuclei appear purple instead of blue after staining, it suggests that the slides were not adequately blued. The Instructions for Use advise using Scott's Tap Water Substitute (catalog number S5134). If warm running tap water was used, it's likely that the slides were not washed for a sufficient duration to convert the purple color to blue. If Scott's Tap Water Substitute was used, it's possible that the old solution needs to be replaced with a freshly diluted 1X solution from the 10X concentrate. Although the official recommendation is for Scott's Tap Water Solution, other blueing solutions are commonly used with different hematoxylin solutions. For instance, 15 grams of sodium bicarbonate per liter of tap or deionized water can be used, or a saturated solution of lithium carbonate. Some have also used a few drops of concentrated ammonium hydroxide in 500 ml of tap or deionized water in the past, but it's important to avoid using too much as it can strip the tissue sections from the glass slides. Typically, the slides are left in the blueing solution until the tissue sections appear blue and not purple. Once the tissue has turned blue, it should be thoroughly washed in running tap water to remove any traces of the blueing solution. Proper removal of the blueing solution is crucial, as leaving traces on the slides will lead to poor staining with Eosin Y solution.

When using SLCH6216, there is light purple/violet staining of nuclei with a gray background in the cytoplasm. Increasing the staining time up to 15 minutes does not result in increased stain intensity. How can this issue be addressed?

The direct replacements for GHS132(1L) would be GHS316 (500mL) and GHS1128(4L). There are other similar formulations that may be of interest. See the list below. Each option includes a link to the product datasheet and the product list for that formulation, respectively.
