FDA808a
FDA normal and tumor organ tissue array of human (2 slide set), replacing FDA808, 144 cases/144 cores, for FDA guidelines to test tissue specificity of antibodies, replacing FDA808
|
|
|
FDA808a-1
Multiple organ normal tissue array, 72 cases/72 cores, replacing FDA808-1
|
|
| Microarray Panel: | Multiple organ normal tissue microarray, 24 common types of normal human organs, including cerebrum, cerebellum, adrenal gland, ovary, pancreas, parathyroid gland, hypophysis, testis, thyroid gland, breast, spleen, tonsil, thymus, bone marrow, lung, cardiac muscle, esophagus, stomach, small intestine, colon, liver, salivary gland, kidney and prostate, each type taken from 3 normal human individuals, single core per case |
| Cores: | 72 |
|
| Cases: | 72 |
| Layout: | 9 cols × 8 rows |
| Core Diameter: | 1.5 mm |
| Thickness: | 5 µm | | Quality Control: | Anti-Actin confirmed | | Applications: | Routine histology procedures including ImmunoHistochemistry (IHC) and In Situ Hybridization (ISH), protocols which can be found on our support page. |
| Notes: | Unless specified, all TMA slides are not coated with extra layer of paraffin (tissue cores can be easily seen on the glass), so there is no need to bake, can be directly put into xylene for de-paraffin procedure. |

FDA808a-2
Multiple organ tumor tissue array with adjacent normal human organs, including TNM, clinical stage and pathology grade, 72 cases/72 cores, replacing FDA808-2
|
|
| Microarray Panel: | Multiple organ tumor tissue microarray with adjacent normal human organs, containing 54 cases of tumor of varieties of organ tissue, plus 18 cases of 6 types of adjacent normal organs, single core per case |
| Cores: | 72 |
|
| Cases: | 72 |
| Layout: | 9 cols × 8 rows |
| Core Diameter: | 1.5 mm |
| Thickness: | 5 µm | | Quality Control: | Anti-Actin confirmed | | Applications: | Routine histology procedures including ImmunoHistochemistry (IHC) and In Situ Hybridization (ISH), protocols which can be found on our support page. |
| Notes: | Unless specified, all TMA slides are not coated with extra layer of paraffin (tissue cores can be easily seen on the glass), so there is no need to bake, can be directly put into xylene for de-paraffin procedure. |
*Tissue Microarray Slide Types:
- Unstained: unstained
paraffin
tissue microarray slide.
- Trial: tissue microarray trial slide. 10% - 25% of cores missing. Good for titrating antibody dilution and experiment conditions. Limited numbers are available, to 2 per item per order. Test slides (tissue arrays with catalog numbers ending with 241 or 242) are recommended as a substitute.
- H & E: Hematoxylin and Eosin stained tissue microarray slide.

† For precise diagnosis, refer to pathology description.
**The grade 1-3 (or I-III) in Pathology Diagnosis is equivalent to well-differentiated, moderately-differentiated or poorly differentiated, respectively, under microscope.
Grade 1 or well-differentiated: Cells appear normal and are not growing rapidly.
Grade 2 or moderately-differentiated: Cells appear slightly different than normal.
Grade 3 or poorly differentiated: Cells appear abnormal and tend to grow and spread more aggressively.
Grade 4 or undifferentiated: *(for certain tumors), features are not significantly distinguishing to make it look any different from undifferentiated cancers which occur in other organs.
TNM grading:
T - Primary tumor
Tx - Primary tumor cannot be assessed
T0 - No evidence of primary tumor
Tis - Carcinoma in situ; intraepithelial or invasion of lamina propria
T1 - Tumor invades submucosa
T2 - Tumor invades muscularis propria
T3 - Tumor invades through muscularis propria into subserosa or into non-peritonealized pericolic or perirectal tissues.
T4 - Tumor directly invades other organs or structures and/or perforate visceral peritoneum
N - Regional lymph nodes
Nx - Regional lymph nodes cannot be assessed
N0 - No regional lymph node metastasis
N1 - Metastasis in 1 to 3 regional lymph nodes
N2 - Metastasis in 4 or more regional lymph nodes
M - Distant metastasis
Mx - Distant metastasis cannot be assessed
M0 - No distant metastasis
M1 - Distant metastasis
