Transfer to a xylene bath and perform two changes of xylene for 5 min. 0 The paraffin-embedded tissue sample is passed through these solvents at various time intervals; and these steps are explained as follows: Mark the sectioned tissue on slide with PAP / pen, and allow to dry. If using HRP-DAB method, skip ABC-HRP step and move to DAB incubation step. Let the slides cool on the bench-top for 30 minutes. The slides are then washed multiple times with xylene … Keep the slides in the tap water until ready to perform antigen retrieval. Continue the incubation overnight at 4°C in a humidified chamber. Wash sections twice in dH2O for 5 minutes each. Block any non-specific binding by incubating the tissue sections with 5% animal serum in PBS-T for 30 minutes at room temperature. Fixing and embedding the tissue 2. (Caution: Oven temperature must not exceed 60 °C). If not specified, the recommended starting dilution is 2-5 µg/ml. h�b```c``*f`f`�`b@ !& �8p���� c��� f;�t �ļ`�]�� �KX|'008�b`�f`�a����iX ��2 ����" �����p(D��@� ��� Currently, and as we abide by local shelter in place orders across the world, we are fully operational and do not anticipate any material supply disruptions across our Bio-Techne brands and product lines. Incomplete removal of paraffin can lead to poor staining of the section. Deactivate and clean work area after use according to manufacturer’s instructions. Note: Use the recommended dilution of the antibody specified on the datasheet. embedded in paraffin before being sectioned.

Wash sections twice with 1% serum in PBS-T for 10 minutes each. If not specified, the recommended starting dilution 2 … To block endogenous peroxidase activity, quench the tissue sections with 3.0% hydrogen peroxide in methanol for 15 minutes. ©2020 Novus Biologicals, All Rights Reserved. Incubate sections in three washes of xylene for 5 minutes each. IHC sample preparation (frozen vs. paraffin-embedded), IHC sample fixation (formalin vs. alcohol). 3. ), skip the following dehydration step and mount in aqueous media instead of organic mounting media. Incubate sections in two washes of 95% ethanol for 10 minutes each. Drying out will cause non-specific antibody binding and therefore high background staining. Agonists, activators, antagonists and inhibitors. Monitor the reaction as the chromogenic reaction turns the epitope sites brown (time of color development may vary from few seconds to 10 minutes). Place the slides in a rack, and perform the following washes using a Coplins jar: Once the slides have been washed in the above sequence, place slides in running cold tap water to rinse off ethanol.
