Prior to use, the hypodermic syringes and needles were dried for several hours in an oven at 100°C and allowed to cool to ambient temperature in a desiccator. 

Using the syringe and needle, gently enter the water down the side of the tube and draw 2 mL into the syringe. 

Each pramlintide dose should be administered subcutaneously into the abdomen or thigh (administration into the arm is not recommended because of variable absorption). Injection sites should be rotated so that the same site is not used repeatedly. The injection site selected should also be distinct from the site chosen for any concomitant insulin injection. Patients should always use a new syringe and needle to give pramlintide and insulin injections. 

Intended for use under the guidance and supervision of the clinician patients may self-inject if appropriate and with medical follow-up, after proper training in injection technique, including proper syringe and needle disposal... 

Using a sterile, nonpyrogenic disposable syringe and needle, inject 5.0 ml of pyrogen-free water to reconstitute the reagent. Reconstitution is more rapid if reagents are at room temperature. 

Withdraw sample from the upper and lower ports of the sample container in intervals specified in the sampling schedule using an appropriately sized syringe and needle. 

Trimethylaluminum was purchased from Aldrich Chemical Company Inc. and obtained as a 2.0 M solution in toluene sealed under nitrogen in a Sure/Seal bottle. Trimethylaluminum is pyrophoric and reacts violently with water and air the syringe and needle used should be rinsed with toluene or hexanes immediately after addition. Note that the rinse, though dilute, contains pyrophoric material and should be handled accordingly. 

Mix well the contents of the Ficoll bottle, wipe the rubber cap with 70% ethanol then inject approx 15 mL air with a 20-mL syringe and needle and withdraw 20 mL of the Ficoll solution. Equally divide the Ficoll solution between two new 50-mL Falcon tubes. 

Intravenous (IV) delivery has two variations injection and infusion. In an injection, the entire dose is rapidly placed in a vein via a syringe and needle. The dose is called an IV bolus. An IV infusion, sometimes called an IV drip, involves administering a drug from an IV bag over a predetermined amount of time. The concentration of the drug solution and IV drip rate determine the eventual drug concentration in the patients blood.

Harvest the cells aseptically using a sterile syringe and needle and sediment them at 800g for 5 min and remove the supernatant (from which monoclonal antibodies may be prepared).
