Tissue Banking Codes

NOTE: HistoBest's letter codes are printed before the number code on all our slides.

First letter stands for the type of achievable applications


C=conventional: fixation was performed in a non-standardized manner by the customer (typically only conventional staining techniques will perform well without further testing and optimization) or

M=multiuse: all procedures are standardized and performed in HistoBest’s laboratory; satisfactory results are attainable for a large variety of applications) or

T=tailored: specialty protocols based on customer’s needs or specifications or

Mm=mixed (some samples are multiuse, some are conventional or tailored).
It applies only for multispecimen preparations

Second letter stands for the design employed in the embedding of the cell/tissue segment(s)

C= conventional: one (C1) or more (Cn) tissue segments are embedded in the usual fashion or

O=conventional, but involving the precise anatomical orientation of one (O1) or more (On) tissue segments or

M=multispecimen: typically 20-100 biopsies are arrayed with HistoBest’s proprietary technique or

I=in situ multispecimen: usually up to 24 biopsies are arrayed in smaller blocks. Their shape is designed for the devices typically used in in situ applications (hybridization, (RT)-PCR, etc.,) or

T= tailored: arrayed cells and/or biopsies. The design is based on customer’s needs or specification
