Histological Processing of Reproductive Tissue Samples

NF-FN7110-21-01495

I. Background/Overview:

NMFS SEFSC Panama City Lab is in need of a non-personal services contract to have fish reproductive tissue samples processed on glass slides with stained tissue sections for histological review. The data obtained through reproductive histology slide readings aid stock assessors in ensuring the sustainability of fish populations. The primary stain that would be needed is hematoxylin and eosin (H&E). However, there may also be a need to use either a Schiff’s- Mallory’s Trichrome stain or periodic acid-Schiff’s hematoxylin with metanil yellow counterstain for some species. Needs will vary by species due to reproductive strategy variations (i.e. hermaphrodites). These stained slides will be used to microscopically determine reproductive status and conditions of fish specimens to meet stock assessment needs, which is essential to NOAA Fisheries’ mission of providing the best scientific data available to manage commercial and recreational fisheries in the Southeast Region of the United States.

The Panama City Lab is performing some comparison studies, which may require specialty stains and/or fixatives. These include samples stored in ExcellPlus fixative, and testing of Schiff’s-Mallory’s Trichrome stain and periodic acid-Schiff’s hematoxylin with metanil yellow counterstain. Vendor must be willing to accept some shipments with specific guidelines provided on comparison needs.

An essential requirement for this contract is that the vendor must be willing to accept pre-labeled slides that show the identification number and inventory barcode to meet Panama City Lab protocols. Vendor must also be willing to accept samples that have been stored long-term in neutrally buffered formalin. Accommodations can be made to ship samples in 70% ethanol solution upon request by the vendor.

II. Scope of Work

The work shall be performed under a contract with firm-fixed-unit prices provided on a per-sample basis for the various types of analyses. The contractor shall provide support on multiple projects for all priced contract line item numbers (CLINS) as set forth in the award. The work is intended to support stock assessments, including those conducted by Southeast Data Analysis Review (SEDAR) on multiple fish species. The maximum number of slides to be processed per year will be 2000. Base year requirement includes a minimum of 1400 slides be processed and returned by July 1, 2021. Total base period NTE 2000 samples.

III. Tasks

Light Microscopy sample processing

1.0 Routine tissue processing for light microscopy on glass slides with histological staining.

1.1 The vendor shall process reproductive tissue from fish species.

1.2 Shall embed tissue in either paraffin or non-electron microscopy (EM) plastics.

1.2.1 The vendor shall accept tissues in cassettes for embedding.

1.2.2 The vendor shall accept trimmed tissues for embedding.

1.2.3 The vendor shall trim fixed tissue to suitable size and orientation for embedding.

1.3 Shall conduct microtomy of the tissue (i.e., sectioning embedded blocks of tissue).

The vendor shall be able to produce routine tissue sections of 5 micrometers that are artifact free and be able to accommodate microtomy at other tissue thicknesses (0.5- 50 micrometers) as requested in the shipping manifest.

1.4 Shall conduct slide preparation, defined by placement of section onto specified type of glass slide (e.g., SuperFrost or SuperFrost Plus) or coated slides (e.g., poly-L lysine, Probe On, Plus Slides, etc.). Special slide requirements will be specified in the shipping manifest.

1.4.1 The vendor shall offer slide preparations that contain one section per block of any particular collection of tissue blocks (e.g., a given case) to assist pathology review by allowing easy comparison across samples. This will be specified in the shipping manifest.

1.4.2 The vendor shall offer slide preparations that place up to 5 sections cut from a given block on one slide. This will be specified in the shipping manifest.

1.5 Shall conduct standard histological staining procedures of tissue sections mounted on glass slides with hematoxylin and eosin (H&E). In addition to routine sample preparation, H&E sections shall also be prepared as a quality control measure for each sample to determine the quality of the fixation and processing of a given sample.

The vendor shall produce H&E sections with even staining, all cytoplasmic and nuclear structures visible within the limitations of light microscopy and no torn or wrinkled sections from both paraffin and plastic embedded tissues, where indicated.

1.6 The vendor shall provide cover slipping of each stained section with a glass coverslip.

1.7 The vendor shall provide a unique identification label for each slide which is clearly visible, readable, and permanent.

1.7.1 Pre-labeled (e.g. barcoded) slides may be provided, and if so, vendor shall maintain standards to ensure correct sample assignment. In the case of pre-labeled slides, matching labels (barcodes) will be present on tissue cassettes.

2.0 Special histological stains

2.1 For established special stains, the vendor shall use industry-standard protocols for the use of special stains with appropriate adaptations for the particular taxa of marine organism being analyzed.

2.2 The vendor shall provide positive control slides as requested. Pre-printed slides designated as control slides will be provided.

2.3 The vendor shall provide a wide variety of the traditional dye stains for comparison studies, including:

2.3.1 Schiff’s-Mallory’s Trichrome

2.3.2 Periodic acid-Schiff stain with metanil yellow counterstain

3.0 Special fixative handling

3.1 Vendor shall handle fixatives other than formalin, including:

3.1.1 ExcellPlus

4.0 The vendor shall have established turnaround times for processing samples post-receipt.

4.1 Routine cases for slide processing will require 2-4 weeks turnaround time, based on number of cases or tissues received with larger numbers (> 400) of blocks necessitating a longer period for processing. The duration for any specific sample will be determined in consultation with the contracting official (or their designee) and specified in the shipping manifest.

4.2 Turnaround time for new techniques or non-traditional tissues may be up to 2 months and duration determined by consultation with contracting official (or designee) and specified in the shipping manifest.

IV. Deliverables

1.0 All glass slides produced shall be delivered to the government’s designated scientific lead or POC in accordance with the instructions provided in each delivery. The slides shall be packaged in such a way as to prevent breakage, insured and shipped by an express carrier (e.g., FedEx, Priority Mail, UPS). Return shipment of the prepared slides shall occur within 30 days upon sample receipt by the vendor.

2.0 Delivery of standard sized (3” x 1”) glass histopathology slides with good to excellent staining of tissues using standard operating procedures for paraffin or non-EM plastic embedded tissue as determined by H&E stained quality control slides. Good to excellent staining is determined by uniformity of staining on section, intensity of stain, and distinction of cellular features (i.e., nucleus, cytoplasm).

3.0 The vendor shall provide their quality control evaluation measures and quality assurance documents for review within 7 days of contract award. The success of any batch of slides shall meet or exceed 85% for staining and section integrity (i.e., devoid of tears, folds, knife marks).
