Low melting point agarose

Manufactured by Leica camera

Low melting point agarose is a type of agarose, a polysaccharide derived from seaweed. It has a lower melting point compared to standard agarose, allowing it to solidify at lower temperatures. This property makes it suitable for applications where a softer, more fragile gel is required, such as in electrophoresis or cell culture procedures.

Animals were either anaesthetized with 0.2 mg/ml MS-222 (PHARMAQ, UK),
or (in case of GCaMP imaging) immobilized with 0.5 mg/ml of the non-depolarizing
neuromuscular junction blocker mivacurium chloride (Abcam). For confocal
microscopy, animals were mounted laterally in 1% ultrapure low melting point
agarose (Invitrogen) on a glass coverslip. The coverslip was flipped over on a
glass slide with a ring of high-vacuum grease filled with a drop of
Danieau’s solution to prevent drying out of the agarose. For lightsheet
microscopy, embryos were mounted upright in low melting point agarose in a
U-shaped glass capillary (Leica). After imaging, the animals were either
sacrificed or released from the agarose using microsurgery blades and kept
individually until further use.

Preparation and Culture of Precision-Cut Lung Slices

Healthy human lung tissue was obtained from Donor Alliance, and IPF tissue was obtained from lung biopsies or explanted lungs from confirmed cases of IPF (IRB 11-1664) as described previously (74 (link)). Tissue from patients with silicosis was obtained after lung transplant as described previously (75 (link)). For the generation of PCLS, freshly explanted healthy or IPF lungs were kept on ice and processed within 24 hours. Peripheral sections of lungs were inflated with low–melting point agarose (MilliporeSigma) by cannulation of a visible bronchus; then 6 × 6 × 6 mm cubes were cut from the lung, embedded in low–melting point agarose, and sectioned using a vibratome (Leica). We cultured 300 μm slices in Eagle minimal essential medium (EMEM, Lonza) with 10% heat-inactivated fetal bovine serum (FBS, Atlanta Biologicals) and 1% penicillin/streptomycin/l-glutamine with or without ABT-263 (5 μM, Medchemexpress) for 24 hours.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
