by: Department of Pathology and Molecular Medicine, McMaster University

No.: #101517

Date: 07/11/2017

Antigen: CD200

Lot Number: AG06145442

Method validated: Immunohistochemistry

Positive Control: Human 7 week normal karyotype elective termination placenta

Negative Control: Placental villus from 7w gestation karyotype-normal pregnancy, stained with KLH antibody ABIN401183

Notes:

Passed. ABIN761396 specifically labels the CD200 in human placental tissue.

Validation Images

Staining with ABIN761396 at dilutions 1:200, 1:250, 1:300, and 1:400 (A, B, C, and D) using a 7 week elective termination of a pregnancy that tested negative for trisomies (Clark et al. (2017) Am. J. Reprod. Immunol). Optimal staining was obtained at 1:200 dilution. Anti-KLH control (E) at 1:200 was negative.

Full Methods

Primary Antibody: ABIN761396

Secondary Antibody: Bond Polymer Refine Detection kit (Leica, DS9800, lot 49232)

Full Protocol:

• Fix human placental tissue in 10% buffered formalin for 24h at RT.
• Process and embed tissue in paraffin.
• Cut paraffin blocks with a Leica CM2255 Microtome into 4µm sections.
• Affix sections to positively charged slides and air dry ON at RT.
• Deway and hydrate the slides on an automated Leica BOND Rx stainer.
• Antigen retrieval on the Leica BOND Rx automated stainer using epitope retrieval buffer 2 (Leica, AR9640, lot ER20172).
• Stain slides with primary
• • Rabbit anti-CD200 antibody (AA 45-95) antibody (antibodies-online, ABIN761396, lot 980502W),
  • rabbit anti-CD200 Receptor 1-Like (CD200R1L) (AA 150-200) antibody(antibodies-online, ABIN1715098, lot 9A13M60), or
  • rabbit anti-KLH antibody (antibodies-online, ABIN401183, lot 304770)
• diluted 1:200 in Power Vision IHC Super Blocker (Leica, PV6122). The staining protocol incorporates a modified Leica standard protocol IHC-F (which omits the post-primary step) and uses the standard times outlined in the machine protocol.
• Stain sections with Bond Polymer Refine Detection kit (Leica, DS9800, lot 49232) containing peroxidase block, post primary antibody, polymer as well as DAB chromogen and hematoxylin counterstain for times outlined in the standard protocol IHC-F.
• Remove slides from the Leica Bond Rx and then dehydrate in ethanol and clear in xylene.
• Mount slides in permount mounting medium (Fisher Scientific, SP15-500, lot 162767).
• After the slide-coverslip edges are dry, scan slides using Imagescope and photograph at 400x.

Experimental Notes:

• Several dilutions from 1:200 to 1:400 of ABIN761396 were tested and 1:200 was found to be optimal.

• The staining pattern of ABIN761396 matches our results with the rabbit anti-CD200 polyclonal antibody RB846 and observations made by others. It is also consistent with staining with the CD200R1L antibody ABIN1715098).
