A. Solutions and Reagents
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
- Ethanol, anhydrous denatured, histological grade (100% and 95%).
- Deionized water (dH2O).
- Hematoxylin (optional).
- Wash Buffer:
- 1X Tris Buffered Saline with Tween® 20 (TBST): To prepare 1L 1X TBST add 100 ml 10X Tris Buffered Saline with Tween® 20 (#9997) to 900 ml dH20, mix.
- SignalStain® Antibody Diluent (#8112).
- 1X Citrate Unmasking Solution: To prepare 250 mL of 1X citrate unmasking solution, dilute 25 ml of SignalStain® Citrate Unmasking Solution (10X) (#14746) with 225 mL of dH2O.
- 3% Hydrogen Peroxide: To prepare 100 ml, add 10 ml 30% H2O2 to 90 ml dH2O.
- Blocking Solution: TBST/5% Normal Goat Serum or 1X Animal-Free Blocking Solution.
- Detection System: SignalStain® Boost IHC Detection Reagents (HRP, Rabbit #8114).
- Substrate: SignalStain® DAB Substrate Kit (#8059).
- Hematoxylin: Hematoxylin (#14166).
- Mounting Medium: SignalStain® Mounting Medium (#14177).
NOTE: Do not allow slides to dry at any time during this procedure.
- Deparaffinize/hydrate sections:
- Incubate sections in three washes of xylene for 5 min each.
- Incubate sections in two washes of 100% ethanol for 10 min each.
- Incubate sections in two washes of 95% ethanol for 10 min each.
- Wash sections two times in dH2O for 5 min each.
C. Antigen Unmasking
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.
- Wash sections in dH2O three times for 5 min each.
- Incubate sections in 3% hydrogen peroxide for 10 min.
- Wash sections in dH2O two times for 5 min each.
- Wash sections in wash buffer for 5 min.
- Block each section with 100–400 µl of preferred blocking solution for 1 hr at room temperature.
- Remove blocking solution and add 100–400 µl primary antibody diluted in SignalStain® Antibody Diluent (#8112) to each section. Incubate overnight at 4°C.
- Equilibrate SignalStain® Boost Detection Reagent (HRP, Rabbit #8114) to room temperature.
- Remove antibody solution and wash sections with wash buffer three times for 5 min each.
- Cover section with 1–3 drops SignalStain® Boost Detection Reagent (HRP, Rabbit #8114) as needed. Incubate in a humidified chamber for 30 min at room temperature.
- Wash sections three times with wash buffer for 5 min each.
- Add 1 drop (30 µl) SignalStain® DAB Chromogen Concentrate to 1 ml SignalStain® DAB Diluent and mix well before use.
- Apply 100–400 µl SignalStain® DAB to each section and monitor closely. 1–10 min generally provides an acceptable staining intensity.
- Immerse slides in dH2O.
- If desired, counterstain sections with hematoxylin (#14166).
- Wash sections in dH2O two times for 5 min each.
- Dehydrate sections:
- Incubate sections in 95% ethanol two times for 10 sec each.
- Repeat in 100% ethanol, incubating sections two times for 10 sec each.
- Repeat in xylene, incubating sections two times for 10 sec each.
- Mount sections with coverslips and mounting medium (#14177).

SDF1 (D8G6H) Rabbit mAb (IHC-Specific) recognizes endogenous levels of total SDF1 protein by immunohistochemistry on paraffin-embedded tissue sections. This antibody recognizes both SDF1α and SDF1β.Species Reactivity: Human
Monoclonal antibody is produced by immunizing animals with recombinant protein specific to human SDF1 protein.
The stromal cell derived factor 1 (SDF1, CXCL12) is a small, pro-inflammatory chemoattractant cytokine that regulates leukocyte trafficking through interactions with its cognate 7-transmembrane G protein-coupled receptors (1). The SDF1 receptor, CXCR4, also serves as a coreceptor for the entry of human immunodeficiency virus into target cells (2). SDF1 may regulate homing and maintenance of CXCR4-expressing stem or progenitor cells, including embryonic and many somatic stem cells (3,4). Many cancer cells express CXCR4, suggesting that SDF1 plays a role in cancer metastasis (5,6). Alternative splicing and differential processing during maturation produce a pair of SDF1 isoforms (SDF1α and SDF1β) that have different properties and biological activities (7). Additional isoforms of SDF1 have been reported (8,9).
