Immersion Oils For Normal Light Microscopy:
Which Type - Which Application?
Cargille PCB-Free Immersion oils were introduced in 1972. Today, no other immersion oil meets FDA criteria. Now four standard types are available with the introduction of Type NVH, a very high viscosity oil. All Cargille Immersion Oils meet DIN 58 884 (Deutsche Institut Fur Normung e.V.)
For Normal Light Microscopy
Types A & B, with viscosities of 150 and 1250cSt respectively, meet these requirements. The greater the gap between cover glass and objective, or condenser and slide, the more desirable high viscosity becomes. For extremely large gaps, type NVH should be used. All Cargille Immersion Oils can be blended for intermediate viscosities.
37°C Immersion
Oils
A number of research projects require microscopic studies at internal body temperature. Since the index/temperature relationship is inverse, increasing temperature significantly reduces the index of the immersion oil and consequently the imagery deteriorates. This problem has been resolved by the formation of Cargille 37°C Immersion Oils, which have an index of 1.515 at 37°C.
Consideration of these oils is also suggested where stage temperatures are elevated by sub-stage illuminators and high wattage projection equipment.
Immersion Oil Type 300
Automated Hematology Systems: Use Type 300; Automated Hematology Systems depend on accurate, precisely controlled physical and optical properties of immersion oil for successful imaging and mechanical processing. Type 300 is designed and manufactured to meet the stringent requirements of this equipment, which include specialized viscosity and exacting controls for its consistency.

Immersion Oils For Fluorescence Microscopy
After years of development and field testing, we now have available two new PCB-Free Immersion Oils for Fluorescence Microscopy.
* Immersion Oil Type HF
Type DF has been discontinued by Cargille. As an alternative we are offering either a new Immersion Oil called HF which would provide low fluorescence and the correct optical properties or you can use our FF which has virtually no fluorescence but slightly less than ideal optical properties.
* Immersion Oil Type FF
Type FF has virtually no background fluorescence which makes it ideal for observing low levels of fluorescence. It is highly stable, water white, and non-hydroscopic. Type FF can be substituted for all other fluorescence microscopy immersion oils in nearly all fluorescence applications.
* Immersion Oil Type LDF
Extremely low fluorescence is achieved by Type LDF. It is the replacement of choice for the DF which is no longer being manufactured. The LDF possesses the highest resolution of the oils for fluorescence applications.

ImmunoHistoZyme™, Ready-to-Use
Description: ImmunoHistoZyme is used for proteolytic digestion of formalin-fixed paraffin-embedded (FFPE) tissue sections prior to application of antibodies. In IHC most commonly used fixative like formalin mask tissue antigens (cellular, membrane and nuclear) by cross-linking process, this results in poor or no staining in IHC. ImmunoHistoZyme digestion of FFPE tissue section improves accessibility of antibodies to tissue antigens.Storage: 2-8°C. DO NOT FREEZE
Intended Use:Use as antigen retriever for some antibodies in IHC. Please refer to primary antibody protocol for IHC.
