Reporting studies. Its distinct genetic makeup often prompts comparisons with the C57BL/6J strain. Mice Handling and Restraint Handling Technique: Tail handling is the standard approach in many Taxonomy and Classification: laboratories and institutions. Kingdom: Animalia Always pay attention to the animal’s breathing and Phylum: Chordata color during restraint. Class: Mammalia Forceps restraint- Used for short-term procedures such as transferring animals to a new cage. Order: Rodentia Scruff restraint- It can be done by one-hand or two- Family: Muridae hand technique. Genus: Mus Application : health assessment, ear-punching, oral Species: The species Mus musculus, commonly known gavage, submandibular blood collection, genotyping as the house mouse, is renowned as one of the most (tail snip) and IP injections (Tuberculin 1cc syringe, 25g extensively researched and recognized species within needle(s) *Max Volume is 10ml/kg*) the Mus genus, which comprises more than 30 distinct Scruff restraint (One-hand technique) - The one-hand species. method places you at greater risk for being bitten Common Strain of Mice Scruff restraint (Two-hand technique)- Hold the mouse 1. BALB/cJ by the base of the tail and remove it from its cage. Type: Inbred Tent Restraint- This hold is commonly used for SC injections (max volume of 2-3cc) The BALB/c strain is an albino, immunodeficient mouse strain known for its ease of breeding and minimal Plexi glass restrainers (tube restrainer)- the mouse is weight differences between males and females. placed in the restrainer either tail or head first. 2. C57BL/6 tail injections (using 1cc Syringe and 27-30g needle(s) Max Volume 0.2ml/kg), , tail warming, and easy access Type: Inbred, black to animal body for other types of injections. The 57BL/6 mice, commonly referred to as "C57 black Decapicone (Saphenous hold)- The animal is placed 6" or simply "Black 6" and abbreviated as 'B6', offer the nose first into the cone, then the plastic is secured benefits of stable strain characteristics and behind them with a twist-tie or tape. straightforward breeding. This hold is commonly used for saphenous vein blood 3. NOD.CB17-Prkdcscid/J sampling or IM injection Type: Mutant Strain (Spontaneous Mutant) Chemical Restraint- achieved by using a gas anesthesia These mice are homozygous for the severe combined such as isoflurane or by a type of injectable sedation immune deficiency spontaneous mutation (Prkdcscid). such as Ketamine/Xylazine mix. 4. DBA/2J Dosage Type: Inbred Mix: Ketamine 80–100 mg/kg Xylazine 8– DBA/2J is a widely utilized inbred strain with 10 mg/kg significance in various research domains such as Buprenorphine 0.3 mg/kg cardiovascular biology, neurobiology, and sensorineural Tribromoethanol 250–300 mg/kg Carprofen 4 mg/kg Maximum volume to be injected in adult mice may be as much as 62 μl but it is recommended that the volume Ketamine 100 mg/kg is kept to 30 μl per nostril. Xylazine 10 mg/kg Intracranial- Via a surgically implanted cerebral cannula, Administration:IP Via direct injection, Via osmotic pump catheter Sexing of pups – checking of the ano-genital distance Intrathoracic administration- Any compound administered percutaneously into the chest requires (female – shorter distance; male – longer distance) animal to be placed under anesthesia.
