NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
NOTE: Do not allow slides to dry at any time during this procedure.
For Citrate: Heat slides in a microwave submersed in 1X citrate unmasking solution until boiling is initiated; follow with 10 min at a sub-boiling temperature (95°-98°C). Cool slides on bench top for 30 min.

Protocol Id: 283
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.
Recommended Fluorochrome-conjugated Anti-Rabbit secondary antibodies:
Cover sections with 4% formaldehyde dilute in 1X PBS.
NOTE: Formaldehyde is toxic, use only in fume hood.
NOTE: All subsequent incubations should be carried out at room temperature unless otherwise noted in a humid light-tight box or covered dish/plate to prevent drying and fluorochrome fading.

Protocol Id: 147
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.
Recommended Fluorochrome-conjugated Anti-Rabbit secondary antibodies:
NOTE: Cells should be grown, treated, fixed and stained directly in multiwell plates, chamber slides or on coverslips.
NOTE: All subsequent incubations should be carried out at room temperature unless otherwise noted in a humid light-tight box or covered dish/plate to prevent drying and fluorochrome fading.

All reagents required for this protocol may be efficiently purchased together in our Intracellular Flow Cytometry Kit (Methanol) #13593, or individually using the catalog numbers listed below.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
NOTE: When including fluorescent cellular dyes in your experiment (including viability dyes, DNA dyes, etc.), please refer to the dye product page for the recommended protocol. Visit www.cellsignal.com for a full listing of cellular dyes validated for use in flow cytometry.
NOTE: Adherent cells or tissue should be dissociated and in single-cell suspension prior to fixation.
NOTE: Optimal centrifugation conditions will vary depending upon cell type and reagent volume. Generally, 150-300g for 1-5 minutes will be sufficient to pellet the cells.
NOTE: If using whole blood, lyse red blood cells and wash by centrifugation prior to fixation.
NOTE: Antibodies targeting CD markers or other extracellular proteins may be added prior to fixation if the epitope is disrupted by formaldehyde and/or methanol. The antibodies will remain bound to the target of interest during the fixation and permeabilization process. However, note that some fluorophores (including PE and APC) are damaged by methanol and thus should not be added prior to permeabilization. Conduct a small-scale experiment if you are unsure.
NOTE: Count cells using a hemocytometer or alternative method.

使用与人精氨酸酶-1 蛋白的 Val47 周围残基相对应的合成肽对动物进行免疫接种来产生单克隆抗体。
L-精氨酸在调节免疫系统方面发挥关键作用 (1-3)。在炎症、癌症和某些其他病理状况下,骨髓细胞分化被抑制,导致出现不成熟的骨髓细胞异质群体,称为骨髓源性抑制细胞 (MDSC)。MDSCs 被募集至癌症相关炎症的位点,并表达高水平的精氨酸酶-1 (4)。精氨酸酶-1 催化尿素循环的最后一步,即将 L- 精氨酸转化为 L-鸟氨酸和尿素 (5)。因此,MDSC 可增加 L-精氨酸的分解代谢,导致癌症炎症微环境中 L-精氨酸的耗减 (4,6)。左旋精氨酸的减少会抑制 T 细胞增殖和功能,因此导致肿瘤进展 (4,6)。精氨酸酶-1 引起了研究人员的极大兴趣,这些研究人员正在寻找治疗靶标以抑制 MDSCs 在癌症免疫治疗中的作用(7)。此外,研究表明,精氨酸酶-1 可将原发性肝细胞癌 (HCC) 与肝脏中的转移性肿瘤区分开来,表明其在 HCC 诊断中可作为潜在生物标记物的价值 (8,9)。
