Blood Sample Collection From Mouse Tail Vein Download Scientific Diagram The tail vein can be used for repeated or serial blood collection. anesthesia. this method can be performed without anesthesia when using a restraint device. procedure. restrain the animal using the mechanical restraint device of your choice with the tail protruding. visualize anatomic landmarks (figures 1 and 2). Place the mouse in a restraint tube and warm the tail using a heated gel pack, light source, or recirculating water blanket to dilate the lateral veins. insert a 1ml syringe and 27g needle into the vein while pulling the plunger back slightly until a flash of blood appears in the hub of the syringe; continue pulling back on the plunger slowly.
Refining Blood Sampling In Mice The volume of blood that may be obtained from the mouse using venipuncture of the submandibular vascular bundle (200 500 µl) is greater than can be safely collected from the tail vein (200 µl maximum). because sampling blood from the submandibular vascular bundle requires minimal restraint and may yield more blood, this is the preferred route. Figure 1 – mice on a heating plate. ensure the sample tube is labelled and open, ready for blood collection. place the rodent into a restraint tube allowing its tail to hang freely. clean the venepuncture site by gently rubbing with an ethanol soaked cotton tip or gauze swab. allow the ethanol to dry. Tail vein sampling is suitable for a small volume of blood (less than 0.2 ml) by puncture (with a needle or lance) of the tail vein. it is suitable for all strains but is more difficult in black or pigmented mice. multiple samples can be taken daily . this technique may be performed with or without anesthesia. this technique. Insert 25 gauge needle at a 10o angle to puncture the vein. for serial collections, a small nick in the tip of the tail using a sharp, sterile scalpel blade is permitted. this technique works well for clot dislodgment and repeat sampling. hemostasis must be ensured. withdraw needle and collect blood drops in capillary tube.

Rodent blood collection 2. blood collection. as with any procedure, training is critically important. the comfort and level of skill of an investigator with a procedure as well as the sample volume and frequency of sampling should be considered when choosing a method. when collecting blood, care must be given not to exceed volumes that. We report the validation of a refined method for repeated blood sampling (up to 3 times at 24 h intervals) in juvenile and adult mice using the tail incision method to sample from the lateral tail vein. this method is not stressful, as assessed by low basal levels of the stress hormone corticosterone. since repeated blood samples can be.
