The antibiotics penicillin and streptomycin are used to prevent bacterial contamination of cell cultures due to their effective combined action against gram-positive and gram-negative bacteria. Penicillin was originally purified from the fungiPenicilliumand acts by interfering directly with the turnover of the bacterial cell wall and indirectly by triggering the release of enzymes that further alter the cell wall. Streptomycin was originally purified fromStreptomyces griseus. It acts by binding to the 30S subunit of the bacterial ribosome, leading to inhibition of protein synthesis and death in susceptible bacteria. This solution contains 10,000 units/mL of penicillin and 10,000 µg/mL of streptomycin.
Gendepot的T4 DNA连接酶是最通用的DNA克隆连接酶。这种ATP依赖性酶将5'-磷酸与3'-羟基化的末端共价连接，这些末端是通过限制性酶消化或其他酶促过程产生的双链DNA片段的平末端或相容的内聚末端。T4 DNA连接酶对单链核酸无活性。连接反应后，可通过在65℃温育10分钟使T4 DNA连接酶失活。
