Lyophilized biological reagents, such as enzymes (e.g., PCR reagents) and antibodies, are provided that include a wax component. Thus, in some aspects, a method is provided for storing a biological reagent comprising formulating the reagent into a lyophilized composition including a wax component. Methods for using such lyophilized reagents are likewise provided.

The present disclosure is directed to compositions, methods and kits for amplifying target nucleic acids while reducing non-specific amplification and undesired amplification products using a dual hot start reaction mixture that comprise at least two different hot start mechanisms.

The present invention relates to a PCR primer facilitating hot-start PCR by suppressing non-specific amplification at room temperature and at the same time capable of reducing significantly non-specific amplification by dominating the amplification of the PCR product rather than the amplification of the original template from the third PCR cycle, more precisely a PCR primer prepared by additionally inserting the reverse-complementary sequence to a certain region starting from the 5-start site of the 5-terminus of the original primer which is composed of priming sequence to anneal to a PCR template into the 5-terminus of the original primer and a PCR method using the same. The primer of the present invention has a original primer sequence composed of priming sequence to anneal to a PCR template and an additional reverse-complementary sequence, which inserted into the 5-terminus of the original primer, to a certain region starting from the 5-start site of the 5-terminus of the original primer sequence, suggesting that a template-specific sequence and its reverse-complementary sequence are included in the same primer. The present invention can improve PCR specificity by reducing non-specific amplification.

Methods for rapidly detecting clinically relevant mutations in the infectious genome of an agent are disclosed. The methods include use of a novel target and temperature dependent RNase H mediated cleavage of blocked DNA primers to initiate isothermal helicase-dependent amplification of a target sequence such as a sequence in the the rpoB gene.
